Maurice Jefferson appeals his conviction and 151-month sentence, imposed after he pled guilty to one count of conspiracy to possess heroin with intent to distribute, in violation of 21 U.S.C. §§ 846, 841. On appeal, Jefferson argues: (1) he should be allowed to withdraw his plea, (2) he does not qualify for the career offender enhancement, and (3) the career offender enhancement’s residual clause is unconsti *590 tutionally vague. After review, we affirm Jefferson’s conviction and sentence.

I.

Jefferson argues, for the first time on appeal, that the magistrate judge failed to adequately explain the elements of the underlying offense of possession with intent to distribute heroin. He claims the magistrate judge’s error goes to one of the core concerns of Rule 11 and constitutes plain error, such that he should be allowed to withdraw his plea.

Jefferson fails to demonstrate plain error. No binding precedent establishes that a magistrate judge’s failure to describe the underlying offense in a conspiracy charge beyond reading the plea agreement and elements of the offense constitutes plain error. See United, States v. Lejarde-Rada, 319 F.3d 1288, 1291 (11th Cir. 2003) (stating there can be no plain error where there is no binding precedent in this Court or the Supreme Court directly resolving the issue). In fact, we have previously held that “[i]n a conspiracy, however, neither actual possession nor actual distribution is a necessary element of the crime.” United States v. Diaz, 190 F.3d 1247, 1253 (11th Cir. 1999).

II.

Jefferson next argues that Fla. Stat. § 843.01 does not constitute a “crime of violence” for purposes of U.S.S.G. § 4B1.2’s residual clause. He concedes United States v. Nix, 628 F.3d 1341 (11th Cir. 2010), cert. denied, - U.S.-, 132 S.Ct. 258, 181 L.Ed.2d 150 (2011), held that § 843.01 constituted a violent felony under the ACCA’s residual clause, but contends that Sykes v. United States, - U.S. -, 131 S.Ct. 2267, 180 L.Ed.2d 60 (2011), has abrogated Nix.

In Nix, we held that a defendant’s conviction for a violation of § 843.01 constituted a violent felony under the ACCA’s residual clause. Nix, 628 F.3d at 1342. 1 We are bound by our decision in Nix because it has not been overruled or abrogated by the Supreme Court or by this Court sitting en banc. See United States v. Kaley, 579 F.3d 1246, 1255 (11th Cir. 2009) (“To constitute an ‘overruling’ for the purposes of this prior panel precedent rule, the Supreme Court decision ‘must be clearly on point.’”). Further, though Jefferson advances arguments as to why Sykes abrogates Nix, Sykes is not clearly on point and does not directly overrule or abrogate Nix. See Sykes, 131 S.Ct. at 2270-77 (holding that an Indiana offense of felony vehicle flight constituted a violent felony for the purposes of the ACCA).

III.

Jefferson argues, for the first time on appeal, that the residual clause of U.S.S.G. § 4B1.2(a)(2) is unconstitutionally vague, relying on Justice Scalia’s dissenting opinion in Sykes. However, Jefferson does not offer any controlling case in this Court or the Supreme Court which establishes that the residual clause of § 4B 1.2(a)(2) is void for vagueness. As a result, Jefferson fails to show that application of the residual clause was plain error. See Lejarde-Rada, 319 F.3d at 1291.

AFFIRMED.
