Lauro Javier Estrada appeals his guilty plea conviction for conspiracy to possess with intent to distribute 1,000 kilograms or more of marijuana. He argues that the district court plainly erred by accepting his guilty plea because there was an insufficient factual basis to support the element of the offense that the conspiracy involved 1,000 kilograms or more of marijuana inasmuch as the Government stipulated that Estrada was responsible for less than 1,000 kilograms of marijuana.

While Estrada moved to withdraw his guilty plea, he did not argue in the district court that there was an insufficient factual basis for the guilty plea. Accordingly, Estrada failed to preserve this issue for review. See United States v. Dunigan, 555 F.3d 501, 506 (5th Cir. 2009). Although Estrada arguably invited or waived the alleged error, out of an abundance of caution, we review the issue for plain error. See United States v. Fernandez-Cusco, 447 F.3d 382, 384 (5th Cir. 2006).

A district court cannot enter a judgment of conviction based upon a guilty plea unless it is satisfied that there is a factual basis for the plea. Fed.R.CRim.P. 11(b)(3). The district court is required “to determine that the factual conduct to which the defendant admits is sufficient as a matter of law to constitute a violation of the statute.” United States v. Marek, 238 F.3d 310, 314 (5th Cir. 2001) (en banc). “[Ijnfer-ences may be ‘fairly drawn’ from the evidence adduced after the acceptance of a guilty plea but before or at sentencing.” United States v. Hildenbrand, 527 F.3d 466, 475 (5th Cir. 2008). Thus, the presen-tence report (PSR), which was adopted by the district court, may be considered. See id.

In a written factual basis, Estrada admitted that he and others “conspired to possess with the intent to distribute 1,000 *443 kilograms or more of marijuana.” He further admitted that he assisted with an operation to transport a load of marijuana that weighed approximately 2,500 pounds, which is approximately 1,133 kilograms. In the PSR, the probation officer reported that the gross weight of the marijuana was 1,114.2 kilograms. Thus, without considering the stipulation to the contrary, Estrada’s admissions contained sufficient facts from which the district court could find that the offense involved 1,000 kilograms or more of marijuana. See id. at 479.

Estrada’s plea agreement and written factual basis included a stipulation that Estrada was responsible for less than 1,000 kilograms of marijuana, arguably contradicting Estrada’s admissions that he conspired to possess with intent to distribute 1,000 kilograms or more of marijuana. The parties cite to no authority concerning whether a contradictory stipulation can negate a factual basis that is otherwise sufficient. As this is an issue of first impression, any error in accepting Estrada’s guilty plea was not plain error. See United States v. Rodriguez-Parra, 581 F.3d 227, 230 (5th Cir. 2009); United States v. Hull, 160 F.3d 265, 272 (5th Cir. 1998).

AFFIRMED.
