PER CURIAM

         Samuel Green appeals the District Court’s order denying his motion for a sentence

reduction under 18 U.S.C. § 3582(c)(2). We will affirm.

                                               I.



    Judge Hardiman has been substituted for Judge Weis.
       We write primarily for the parties, who are well acquainted with this case, so we review

only briefly the essential facts and procedural history.

       In 1994, Green was convicted of possession with intent to distribute crack cocaine in

violation of 21 U.S.C. § 841(a)(1) and (b)(1)(B)(iii). Green was also convicted of using a

firearm during a drug trafficking crime and possession of a firearm by a prohibited person, in

violation of 18 U.S.C. §§ 924(c) and 922(g)(1), respectively.      Green qualified as a career

offender under § 4B1.1 of the United States Sentencing Guidelines and his total offense level

of 35 and criminal history category of VI produced an imprisonment range of 292 to 365

months. The District Court sentenced Green to 360 months imprisonment for the crack

cocaine offenses.

       At issue here is Green’s motion for a reduction in sentence under § 3582(c)(2). In his

motion, Green sought a reduction in light of Sentencing Guidelines Amendment 750, which

“reduced the crack-related offense levels in § 2D1.1 of the Guidelines” and Amendment 759,

which made Amendment 750 retroactive. United States v. Berberena, 

, 517-18

(3d Cir. 2012). Green also argued that he was entitled to a sentence reduction because his

“career offender criminal history significantly over-represents the seriousness of [his] crime.”

The District Court denied Green’s motion in a memorandum order and explained that Green

was not entitled to relief under § 3582(c)(2) because Amendment 750 changed the base offense

levels for most crack offenses but does not apply to the offense levels applicable to career

offenders.   Consequently, the District Court stated it could not reduce Green’s sentence

because doing so would contravene the Sentencing Guidelines’s binding policy statement,


                                              2
§ 1B1.10, which limits the application of a retroactive amendment to those cases where the

amendment results in a lower imprisonment range. Further, the District Court noted that

Green’s argument that his career offender classification over-represented his criminal history

was not a cognizable basis for relief under § 3582(c)(2).

                                                 II.

       We have jurisdiction under 28 U.S.C. § 1291. Our review of the District Court’s

interpretation of the Sentencing Guidelines is de novo. United States v. Sanchez, 

, 277-78 (3d Cir. 2009).       We review the District Court’s ultimate disposition of a

§ 3582(c)(2) motion for abuse of discretion. United States v. Mateo, 

, 154 & n.2

(3d Cir. 2009).

                                                 III.

       On appeal, Green did not brief his claim that his classification as a career offender over-

represented his criminal history and this argument may be deemed waived and abandoned.

Kost v. Kozakiewicz, 

, 182 (3d Cir. 1993). Nevertheless, we agree with the District

Court that § 3582(c)(2) precludes relief on that basis. As the District Court noted, relief under

§ 3582(c)(2) is limited to aspects of Green’s sentence affected by a change to the Sentencing

Guidelines. See Dillon v. United States, 

, 2694 (2010). Further, although

Green argued in his response to the Government’s reply to his motion that the District Court

incorrectly designated him a career offender, this argument was not briefed on appeal and is

deemed waived and abandoned. 

.

       Green’s request for a sentence reduction is foreclosed by our existing precedent. As the


                                             3
District Court noted, a sentencing reduction under § 3582(c)(2) is available only if, inter alia,

the defendant was “sentenced to a term of imprisonment based on a sentencing range that has

subsequently been lowered by the Sentencing Commission.” 18 U.S.C. § 3582(c)(2); see also

United States v. Thompson, 

, 287 (3d Cir. 2012). This language permits a

reduction on the basis of a Sentencing Guidelines amendment only if the amendment “ha[s] the

effect of lowering the sentencing range actually used at sentencing.” 

(internal quotation marks omitted); see also U.S.S.G. § 1B1.10(a)(2)(B). For example, in

United States v. Mateo, the defendant’s offense level was determined by his career offender

status, not by the lower offense level dictated by the crack cocaine quantity, so his sentence

remained the same even with application of the amendment at issue, Amendment 706. 

. The same is true in this case: Green’s sentencing range of 292 to 365

months of imprisonment is unchanged by the application of Amendment 750. Amendment

750 altered the ranges contained in U.S.S.G. § 2 D1.1 that lists the base offense levels for crack

cocaine quantities. Amendment 750 did not amend the ranges contained in U.S.S.G. § 4B1.1

that lists offense levels and guideline ranges for career offenders and was used to sentence

Green, not § 2D1.1.

       In his brief, Green argues that Dorsey v. United States, 

(2012), instructs

that Amendment 750 is applicable to his sentencing determination. Green’s reliance on Dorsey

is misplaced. In Dorsey, the United States Supreme Court held that the Fair Sentencing Act,

124 Stat. 2372, which was passed in 2010 and reduced the disparity between penalty

provisions for crack cocaine versus powder cocaine, applied to defendants who committed


                                             4
offenses prior to the enactment of the Act but were sentenced after it became effective. 132 S.

Ct. at 2326, 2336. Dorsey did not alter the principle that a defendant is only entitled to a

sentence reduction if an amendment altered the sentencing guidelines that were actually used at

sentencing.1 See 

. Consequently, Green is not entitled to a sentence

reduction on the basis of Amendment 750 and the District Court did not abuse its discretion in

denying Green’s § 3582(c)(2) motion.

       Accordingly, we will affirm the judgment of the District Court.

  Green also relies on United States v. Poindexter, 

(E.D. Pa. 2008), for the
proposition that a career offender’s sentence can be reduced pursuant to an amendment
modifying crack cocaine guidelines. However, his interpretation of Poindexter is incorrect. In
Poindexter, the defendant was not sentenced as a career offender but rather was sentenced
pursuant to U.S.S.G. § 2D1.1 and therefore was entitled to a sentence reduction. 

at 581-82. The court even explained that the defendant would not have been entitled to a
sentence reduction if he had been sentenced as a career defender because in that case “the drug
quantity table [in U.S.S.G. § 2D1.1(c)] does not figure into the guideline range calculus and so
a modification of that table cannot have the effect of lowering the defendant’s sentence.”
