OPINION AND ORDER

I. INTRODUCTION

Plaintiffs Vladimir Hrunov and Andrey Ryabinskiy are Russian boxing promoters who do business as World of Boxing (“WOB”). Defendant Don King (“King”) is an American boxing promoter who does business as Don King Productions. On January 28, 2014, King and WOB entered into an Agreement In Principle (“Agreement”), in which King promised to produce Guillermo Jones (“Jones”) for a bout against Denis Lebedev (“Lebedev”) on April 25, 2014.1 The day the bout was supposed to take place, Jones tested posi*509tive for furosemide, an illicit, performance-enhancing diuretic. The positive drug test precluded Jones from competing, and the bout was called off.

On May 28, 2014, WOB filed this suit. WOB alleges that King, by failing to produce a clean fighter, breached the Agreement.2 King makes two arguments in his defense. First, he argues that the Agreement only required him to “do everything within his control ... to cause Jones’s participation”3 — because Jones’s use of fu-rosemide was not within King’s control, it cannot be grounds for breach. Second, King argues that even if he did breach the Agreement, his failure to perform should be excused because performance was impossible. King has also filed two counterclaims, alleging that, in fact, WOB was the party responsible for violating the Agreement.4

On August 22, 2014, WOB moved for partial summary judgment on the question of contract liability. WOB seeks (1) a ruling that King is liable for breaching the Agreement, (2) dismissal of King’s counterclaims, and (3) a judgment that WOB is entitled to reimbursement of funds from a disputed escrow account (“escrow funds”).5 For the reasons set forth below, WOB’s motion is GRANTED as to liability, and GRANTED as to the dismissal of King’s counterclaims. However, judgment on the escrow funds is reserved.6

II. BACKGROUND

The following facts are undisputed. On May 17, 2013, Jones and Lebedev fought in a Cruiserweight Title Fight in Moscow, sanctioned by the World Boxing Association (“WBA”), which Jones won by knockout in the eleventh round.7 After the bout,however, Jones’s urine tested positive for furosemide, prompting an investigation by the WBA. On October 17, 2013, the WBA found Jones guilty of using a banned substance, stripped him of the Cruiserweight title, and suspended him from WBA-sanctioned bouts for six months.8

On January 28, 2014, King and WOB finalized terms for a second administration of the Cruiserweight Title match between Lebedev and Jones. In the Agreement, King represented that he “holds the exclusive promotional rights for Jones,”9 and he promised to “cause Jones [ ] to participate” in the rematch.10 The Agreement also imposed the following restrictions on Jones:

Jones must arrive in Moscow a minimum of 7 days before the Event and shall remain in Moscow until the Event. Jones also undertakes to be subjected to drug testing before and after the fight, *510in compliance with the rules of the WBA and the [2013 WBA Resolution].11

The purpose of these provisions, as King has explained by affidavit, was to “preclude another [ ] positive drug test [from Jones].”12

The rematch was finalized for April 25, 2014. On April 23, 2014, urine samples were collected from both Jones and Lebe-dev and submitted for testing. On April 25, 2014 — the day the bout was supposed to take place — a report was issued, finding that Lebedev’s sample was clean but that Jones’s sample tested positive for furosem-ide. When WOB and Lebedev learned of this news, Lebedev withdrew from the bout.13 On April 28, 2014, the WBA issued a letter deeming Lebedev’s withdrawal “justifiabl[e]” on the basis that “[t]he WBA would not, and could not, sanction a championship bout when it was aware of Jones’ positive test as this would violate WBA rules, may cause unnecessary harm to [Le-bedev], and would otherwise compromise the nature of WBA world title bouts.”14 On May 23, 2014, after reviewing the test results more carefully, ,the WBA issued a resolution (1) affirming the finding that Jones’s urine contained furosemide, (2) suspending Jones from WBA-sanctioned bouts for two years, and (3) naming Lebe-dev Cruiserweight champion.15

On May 28, 2014, WOB brought the present suit. It argues that King, by failing to “cause Jones [] to participate” in the bout, breached the terms of the Agreement.16 King has counterclaimed, asserting breach by WOB.17 He argues that Lebedev’s decision to “unilaterally” withdraw18 — after learning of Jones’s positive drug test — violated the terms of the Agreement.

*511III. STANDARD OF REVIEW

Summary judgment is appropriate “where, construing all the evidence in the light most favorable to the [non-moving party] and drawing all reasonable inferences in that party’s favor, there is ‘no genuine issue as to any material fact and ... the [moving party] is entitled to judgment as a matter of law.’ ”19 “A fact is material if it might affect the outcome of the suit under the governing law, and an issue of fact is genuine if the evidence is such that a reasonable jury could return a verdict for the nonmoving party.”20 In deciding a motion for summary judgment, “[t]he role of the court is not to resolve disputed issues of fact but to assess whether there are any factual issues to be tried.”21

IV. APPLICABLE LAW

“Because this is a diversity action,” the Court applies the law of “the forum in which [it] sits.”22 Here, the Agreement provides that it “shall be interpreted, construed, and enforced in accordance with the laws of the State of New York.”23 Therefore, New York law governs.

A. Breach of Contract

Under New York law, contracts are given “the meaning intended by the parties, as derived from the language of the contract in question.”24 Contract construction is not simply a matter of examining “literal language.”25 It requires courts to consider what can be “reasonably implied” from the contract’s language, in order to determine what “a reasonable person in the position of the promisee would be justified in understanding [the contract to] include[ ].”26 As a matter of law, if a contract makes reference to extraneous rules or regulations, the content of those rules or regulations is incorporated into the contract’s terms.27

Breach of contract claims are subject to a four-part test. To prevail, a plaintiff must show: “(1) the existence of a contract between [the plaintiff] and [the] defendant; (2) performance of the plaintiffs obligations under the contract; (3) breach of the contract by [the] defendant; and (4) damages to the plaintiff caused by [the] defendant’s breach.”28 Here, the only element in dispute is the third prong of the test.

B. The Defense of “Impossibility”

Breaches of contract normally carry *512“strict liability.”29 However, a breach can be excused — and liability extinguished — if the breaching party can show that performance was impossible on account of a “supervening event” whose “non-occurrence of that event [was] a ‘basic assumption’ on which both parties made the contract.” 30

To sustain an impossibility defense, the “supervening event” must have been “unanticipated” by the parties.31 As the Supreme Court has explained, if an event “was foreseeable,” it “should have been [provided] for it in the contract, and the absence of such a provision gives rise to the inference that the risk was assumed” by the party whose performance was frustrated.32 In other words, an impossibility defense only excuses non-performance if the “unanticipated event [] could not have been foreseen or guarded against in the contract.”33

V. DISCUSSION

A. King Breached the Contract

The Agreement required King to “cause [Jones] to participate in a 12 Round WBA Cruiserweight World Title match [against Lebedev].”34 King argues that this clause is ambiguous, and that its meaning depends on unresolved factual questions, making summary judgment inappropriate.

But the relevant facts are not in dispute. Under WBA rules — which the Agreement incorporates by reference — any boxer who tests positive for a banned, performance-enhancing substance is disqualified from WBA-sponsored bouts for no less than six months.35 Both parties agree that Jones ingested furosemide,36 and there is no question that having tested positive for furosemide, Jones could not participate in the bout.37 This ends the inquiry. If Jones could not participate in the bout, it follows a fortiori that King could not have caused Jones to participate in the bout. Therefore, King breached the Agreement.38

*513King protests that this interpretation of the Agreement yields “unreasonable and illogical” results.39 It would require of King “nothing less than ... personal supervision. of Jones’s every action between the execution of [the Agreement] and the scheduled date of the [bout against Lebe-dev].” 40 Indeed, in order to avoid liability, King avers that he would have had “to imprison Jones to prevent him from having any access to a banned substance”41— clearly an untenable outcome.

While these arguments might have force, they are addressed to the wrong issue. King could be right: under the circumstances, it is possible that his contractual obligations were too onerous to be enforceable. But that question goes to whether King’s failure to perform may be excused, not to whether King in fact failed to perform.42 As to the latter, Jones’s disqualification plainly put King in breach.

B. Impossibility Does Not Excuse King’s Breach

In general, “contract liability is strict liability.”43 Nevertheless, failure to perform can be excused if “destruction of ... the means of performance makes performance objectively impossible.”44 In this vein, King likens his plight to that of a singing troupe manager who signed a contract with a theater owner, promising that the troupe would play for two weeks, only to have the lead singer fall ill on the eve of the first show. When the theater owner sued for breach, the New York Court of Appeals excused the manager’s non-performance on the grounds that “[c]ontracts for personal services” — contracts that require action by a specific person — “are subject to [the] implied condition[] that ... if [the person] dies, or without fault on the part of the covenantor becomes disabled, the obligation to perform is extinguished.”45 Likewise here, argues King: by ingesting furosemide, Jones “disabled” himself from participating in a WBA-sponsored bout, thereby “extinguishing” King’s obligation to perform.

New York law is very clear, however, that an impossibility defense is only available if the frustration of performance was “produced by an unanticipated event that *514could not have been foreseen or guarded against in the contract.”46 In this case, two key facts compel the conclusion that Jones’s ingestion of furosemide was not “unanticipated” — i.e., that King should have foreseen the possibility of Jones testing positive and guarded against it in the contract. First, Jones had a history of doping. The result of the first Cruiser-weight Title match between Jones and Le-bedev — in May 2013 — had to be vacated because Jones tested positive for furosem-ide after the fact.47 Second, the Agreement provided for mandatory pre-bout drug testing,48 as required by the 2013 WBA Resolution.49

King tries to "turn these facts around. Noting how “stunned” and “shocked” he was to learn of the positive drug test -on April 25, 2014,50 King reports that “it de-fie[d] belief, that Jones, aware that • he would be subjected to pre-bout drug testing due to his previous positive result, would again test positive for the same banned substance.”51 Put otherwise, King “believed that the mandatory drug testing provision ... would preclude another potential positive drug test, because [Jones] knew that [he] would be subject to random [] testing.”52 Therefore, in King’s view, he should not ]pe punished for failing to foresee such a “plainly remote and unlikely event.”53

While King’s dismay is understandable — it is stunning that Jones was foolish enough to test positive for the same drug twice — his argument misconstrues the term “unanticipated event.” Ipng casts the question in terms of probability: an event is “ilnanticipated,” in his view, if it is unlikely to occur. What the case law has in mind, however, are not improbable events, but events that fall outside the sphere of what a reasonable person would plan for.54 Even assuming that King is right about the likelihood of a second positive test, _ it strains credibility to call the event “unanticipated.”

King’s own testimony proves the point. By way of explaining why the Agreement was silent about what to do in the event of a second positive test, King admits that he thought the “mandatory drug testing provision” would “preclude” Jones from ingesting furosemide.55 No doubt he did. From this testimony, however, no one could reasonably conclude that King had not anticipated the possibility of a second positive test. Rather, the inescapable conclusion is that King had anticipated such a possibility — and having anticipated it, he believed the threat of a mandatory drug test would ward it off. That King’s belief turned out to be mistaken is no basis for relieving him of his contract obligations.

In essence, King argues that he should not be held liable because Jones’s decision to take furosemide was outside of King’s *515control: short of “imprisoning] Jones,”56 there was no way for him to perform. But this argument ignores what was in King’s control: the decision not to bargain for more protective contract terms.

After all, WOB could also invoke the “imprisonment” logic — in support of the opposite view. If I were to rule that Jones’s ingestion of furosemide effectively dissolved the Agreement, and that King’s failure to perform was therefore excused, WOB might reasonably object that it had no way — short of imprisoning Jones — to avoid the economic loss of that outcome. Ultimately, the reality is that Jones’s poor decision-making was costly to both parties. The question is which party — King or WOB — should have to shoulder those costs. The law makes it clear that the answer is King. As the party who promised to secure Jones’s participation, King “assumed the risk” of foreseeable events that might frustrate his ability to make good on that promise.57 Because the risk of a second positive test was foreseeable— so foreseeable, in fact, that the Agreement set out a mandatory testing provision to lessen its likelihood — King’s breach cannot be excused.

C. King’s Counterclaims Fail

Both of King’s counterclaims rest on the proposition that Lebedev’s decision to withdraw from the bout constituted either a breach or a dissolution of the Agreement, releasing King from his obligations. This proposition is wrong. Once Jones tested positive, WOB and Lebedev were entitled to “treat the entire contract as broken,” because Jones’s participation (which the positive test rendered impossible) was the centerpiece of the agreement.58 In other words, King’s argument that Lebedev breached the Agreement necessarily fails, because the Agreement had already been breached — by King— when Lebedev withdrew. King’s counterclaims are therefore dismissed.

VI. CONCLUSION

For the foregoing reasons, WOB’s partial motion for summary judgment as to liability is GRANTED. The Clerk of the Court is directed to close this motion (Dkt. No. 26), and the parties are directed to submit briefings as to damages in accordance with the following schedule: WOB’s moving papers (15 pages) should be filed by October 10; King’s opposition (15 pages) should be filed by October 17; and WOB’s reply (5 pages) should be filed by October 24.

SO ORDERED.
