In the co-main event, champion Aljamain Sterling retained his title in a dominant showing against an injured T.J. Dillashaw, finishing the fight by TKO in the second round.

The feature bout between Sean O’Malley and former champion Petr Yan also played a big part in the bantamweight divisional shakeup. O’Malley emerged victorious by split decision in a close three-round battle.
