The French Commission for the Bellator Paris title defense against Magomed Magomedov in May 2024 was reported to have announced that Mix failed a drug test, specifically testing for marijuana prior to his successful title defense. The French commission overturned the fight result 17 months later due to the drug test failure, resulting in a loss for Mix. Despite this, Mix's official record still includes the victory against Magomomov, according to the Association of Boxing Commissions and Combative Sports. Mix, who had already left Bellator and joined the UFC, has criticized the French commission for its decision to overturn his victory and stated that he should seek a defamation of character lawsuit against them.
