MJF made a dramatic return to All Elite Wrestling at Grand Slam Mexico on Wednesday night, attacking Andrade El Idolo shortly after he had won a triple-threat match. The interruption sets up a potential rivalry heading into All In later this month and signals MJF's intent to be involved in the upcoming casino gauntlet match.

Andrade earned the number one spot in the casino gauntlet match by winning a triple-threat contest, but before he could celebrate, MJF emerged from the crowd and struck him with the AEW World Championship's Triple B title belt. The ambush marks MJF's latest return to AEW programming and positions him as a factor in the build towards All In.
