Alfredo Flores appeals the 150-month prison sentence the district court 1 imposed upon his guilty plea to conspiracy to distribute and possess with intent to distribute marijuana and cocaine, in violation of 21 U.S.C. § § 841(a)(1), and 846. For reversal, Flores argues that Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), effectively overruled Almendarez-Torres v. United States, 523 U.S. 224, 118 S.Ct. 1219, 140 L.Ed.2d *550 350 (1998), and that the district court therefore violated his Fifth and Sixth Amendment rights in finding that his prior controlled-substanee convictions qualified him for sentencing as a career offender under U.S.S.G. § 4B1.1. Flores’s argument fails as we are still bound by Almendarez-Torres. See United States v. Torres-Alvarado, 416 F.3d 808, 810 (8th Cir. 2005) (“we are bound by Almendarez-Torres until the Supreme Court explicitly overrules it”); see also United States v. Marcussen, 403 F.3d 982, 984 (8th Cir.) (holding that district court, not jury, determines whether prior convictions subject defendant to be sentenced as career offender), cert. denied, — U.S. -, 126 S.Ct. 457, 163 L.Ed.2d 347 (2005).

Accordingly, we affirm.
