UFC 303 is taking place on Saturday from T-Mobile Arena in Las Vegas, and the event headlines International Fight Week. The card was originally supposed to be headlined by Conor McGregor’s highly anticipated return against Michael Chandler, but an injury to McGregor forced a late shakeup. Alex Pereira will instead defend the UFC light heavyweight title on very short notice against Jiri Prochazka in a rematch. Pereira beat Prochazka by TKO at UFC 295 in November 2023 to originally claim the title.
The co-main event has also experienced a late shakeup, as Jamahal Hill was forced to withdraw due to a knee injury.
