On June 30, 1997, a jury convicted Romaine Dukes of one count of conspiring to distribute cocaine base and two counts of distributing cocaine base. Because of the drug quantity involved and Dukes’ two prior felony drug convictions, he was sentenced to a mandatory life term of imprisonment on the conspiracy count and on one distribution count, and to ten years’ imprisonment on the other distribution count. This court affirmed the direct appeal of his conviction. United States v. Dukes, 147 F.3d 1033 (8th Cir. 1998). After the Supreme Court rendered its opinion in Jones v. United States, 526 U.S. 227, 119 S.Ct. 1215, 143 L.Ed.2d 311 (1999), but prior to its opinion in Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000), Dukes petitioned for habeas corpus relief pursuant to 28 U.S.C. § 2255, which the district court 2 denied, and upon which we ultimately issued a certificate of appealability. 3 Because Dukes is precluded from raising Apprendi errors on collateral review, we affirm the judgment of the district court.

Dukes’ challenge under Jones encompasses the issue the Court definitively addressed in Apprendi. See United States v. Moss, 252 F.3d 993, 995 (8th Cir. 2001). In Apprendi, the Court held that, with the exception of prior convictions, any fact that increases the penalty for a crime beyond the maximum statutory penalty must be submitted to a jury and proven beyond a reasonable doubt. 120 S.Ct. at 2362-63; see also United States v. Nordby, 225 F.3d 1053, 1057 (9th Cir. 2000) (“Apprendi v. New Jersey is the latest in a series of cases in which the Supreme Court has expressed a heightened concern that the determination of ‘sentencing factors’ by a judge using a preponderance-of-the-evidence standard implicates the accused’s right to due process under the Fifth Amendment and right to a jury trial under the Sixth.”). We have held that, when drug quantity has not been alleged in the indictment and found beyond a reasonable doubt by a jury, Apprendi precludes imposition of a sentence in excess of the maximum prescribed by 21 U.S.C. § 841(b)(1)(C). United States v. Bradford, 246 F.3d 1107, 1113 (8th Cir. 2001); United States v. Aguayo-Delgado, 220 F.3d 926, 933 (8th Cir. 2000).

Although we retroactively apply Apprendi in cases on direct appeal, United States v. Anderson, 236 F.3d 427, 429 (8th Cir. 2001), this court has recently concluded that Apprendi presents a new rule of constitutional law that is not of “watershed” magnitude and, consequently, petitioners may not raise Apprendi claims on collateral review. Moss, 252 F.3d 993, 995 (relying upon Teague v. Lane, 489 U.S. 288,109 S.Ct. 1060, 103 L.Ed.2d 334 (1989) (plurality)). Furthermore, even if petitioners could collaterally attack their sentences based on Apprendi, in Moss this court also determined that failure to make that challenge in a direct appeal proeedurally bars its assertion on collateral review. Id. at 995,1003.

While the Supreme Court has not spoken on the issues decided in Moss, 4 we are *914 bound by that decision. United States v. Reynolds, 116 F.3d 328, 329 (8th Cir. 1997) (“One panel may not overrule another.”). Although in this case there may be sufficient bases for overcoming the procedural bar, we find no way around Moss’ prohibition on retroactive application. Therefore, we are unable to reach the merits of Dukes’ claim.

Accordingly, the judgment of the district court is affirmed.
