PER CURIAM.

       Derek Harvey pleaded guilty to a two-count indictment charging him with
possessing with intent to distribute a mixture or substance containing heroin, in
violation of 21 U.S.C. § 841(a)(1) “and punishable under Section 841(b)(1)(B)(i)”; and
using or carrying a firearm during and in relation to a drug-trafficking crime, in
violation of 18 U.S.C. § 924(c). The district court1 sentenced him to 210 months
imprisonment for the drug offense (the Guidelines minimum), a mandatory consecutive

        The Honorable Charles A. Shaw, United States District Judge for the Eastern
District of Missouri.
60-month prison term for the firearm offense, and concurrent 4-year and 3-year terms
of supervised release. Harvey appeals.

       We reject seriatim each of the arguments raised by Harvey and his counsel.
First, Harvey’s plea-withdrawal motion--premised on his alleged unawareness that he
would be sentenced as a career offender and on alleged promises by the authorities--
was properly denied. See United States v. Ludwig, 

, 950-51 (8th Cir.
1992) (defendant’s unawareness of applicability of career-offender provision did not
constitute fair and just reason to allow him to withdraw his guilty plea); cf. United
States v. Kelly, 

, 618-19 (8th Cir. 1994) (district court did not abuse
discretion in denying plea-withdrawal motion premised on government’s refusal to
move for substantial-assistance downward departure where government did not breach
plea agreement or unconstitutionally withhold motion).

      Second, Harvey’s claim that he provided substantial assistance to the authorities
did not present a valid basis for a downward departure. See United States v. Fountain,

, 928 (8th Cir. 2000) (U.S.S.G. § 5K1.1 departure requires government
motion, and defendant cannot avoid this requirement by moving for U.S.S.G. § 5K2.0
departure based on substantial assistance). Third, the district court did not plainly err
in failing to depart on the basis that Harvey's criminal history category was
overrepresented, see U.S.S.G. § 4A1.3, an issue raised for the first time on appeal. See
United States v. Montanye, 

, 192 (8th Cir. 1993) (en banc) (standard of
review for issues not raised below).

       Fourth, we reject Harvey’s argument that the district court plainly erred by
classifying him as a career offender because we conclude that his 1984 Missouri
manslaughter conviction constituted a crime of violence. See U.S.S.G. § 4B1.2 cmt.
1 (1998) (manslaughter is crime of violence); United States v. Leeper, 

,
753 (8th Cir. 1992) (manslaughter by definition means someone has been killed and
thus includes use of force and constitutes crime of violence).

                                           -2-
      Finally, Harvey argues that the district court should have ruled on a particular
drug quantity. However, the indictment to which he pleaded guilty specified that the
offense was “punishable under [21 U.S.C. §] 841(b)(1)(B)(i),” and the prosecutor
explained the corresponding imprisonment range at the change-of-plea hearing. See
United States v. Nguyen, 

, 783 (8th Cir. 1995) (defendant who explicitly
and voluntarily exposes himself to specific sentence by pleading guilty may not
challenge that punishment on appeal).

      Accordingly, we affirm the judgment of the district court.
