Per Curiam.
Appellant, Qavontae MacHell Lang, contends in part that we should reverse his convictions based on ineffective assistance of counsel that is apparent on the face of the record. Except in rare cases, allegations of ineffective assistance of trial counsel must be raised in a postconviction proceeding brought pursuant to Florida Rule of Criminal Procedure 3.850, not on direct appeal. See Barnett v. State , 181 So.3d 534, 536 (Fla. 1st DCA 2015). We reject Appellants argument that this case meets that rare standard. While Appellant also raises what he characterizes as a double jeopardy argument, he challenges his two fifteen-year sentences, not his convictions. See State v. Williams , 854 So.2d 215, 217 (Fla. 1st DCA 2003) (noting that a double jeopardy claim constitutes, in reality, a challenge to [the appellees] convictions rather [than] his sentence). Because Appellant did not preserve this argument, we cannot address it. See Sims v. State , 998 So.2d 494, 504 (Fla. 2008) (In Florida, a specific, contemporaneous objection is necessary to preserve a sentencing error.). Our disposition does not preclude Appellant from challenging his sentences in a motion filed pursuant to Florida Rule of Criminal Procedure 3.800(a). See Eason v. State , 932 So.2d 465, 466 (Fla. 1st DCA 2006) (noting that the appellant, who completed youthful offender boot camp, argued in his rule 3.800(a) motion that the trial court erred in sentencing him following his violation of probation). Finally, we have considered Appellants remaining arguments, which we find to be meritless.
