Red Bull KTM Factory Racing said MRI scans confirm Aaron Plessinger has suffered a hip labral tear and that he is likely to miss the remainder of the Monster Energy AMA Supercross Championship. The injury was sustained in a heavy crash in the Birmingham main event after an earlier big crash in Indianapolis, and the team said the tear will require intensive treatment and an extended recovery.

Plessinger, who sat out the Detroit round while aiming to return for Round 12 in St. Louis, called the diagnosis “a gut punch” and said he accepted the decision so he can recover fully and “give it my best.” KTM said Plessinger faces a potential six-week absence; if he is not cleared before Supercross concludes, his focus will shift to rehabbing and preparing for the AMA Pro Motocross Championship.

Plessinger is 12th in the championship standings with a season-best sixth at Daytona. KTM framed the decision around long-term recovery and team planning; teammates Eli Tomac and Jorge Prado will continue to represent the factory squad at St. Louis while the team manages Plessinger’s treatment and the timing between Supercross recovery and outdoor preparations.
