Until just over two weeks from the event, the selling point of UFC 303 was "Conor McGregor is back." That all changed when weeks of speculation over a potential McGregor withdrawal was confirmed with the UFC announcing the Irish superstar was off the International Fight Week card. The UFC rebounded from the situation by scheduling a light heavyweight championship rematch between champ Alex Pereira and the man he defeated to win the belt, Jiri Prochazka.

Prochazka won the title at UFC 275, winning an outstanding fight against Pereira's friend and MMA mentor Glover Teixeira but was forced to vacate the title due to injury before defending it even once. Prochazka's comeback fight was with Pereira for the vacant title, which Pereira won by TKO in the second round.

In addition to being the current light heavyweight champion, Pereira is also a former middleweight champion and has achieved all of that in just 12 professional MMA fights.

Another former light heavyweight champion was also scheduled to be on the card, with Jamahal Hill taking on Carlos Ulberg. Hill was forced off the card due to injury -- announced at the same time as the McGregor injury -- and Ulberg moved down the card where he'll face former title challenger Anthony Smith.

The new co-main event sees Brian Ortega take on Diego Lopes in a featherweight clash.
