Watch new UFC 303 promo headlined by Alex Pereira vs. Jiri Prochazka rematch

Alex Pereira and Jiri Prochazka are helping the UFC ensure the show goes on.

A trailer for the revised UFC 303 pay-per-view event on June 29 has been released, featuring a rematch between light heavyweight champion Pereira and rival Prochazka. The two are stepping in on short notice to give the International Fight Week capper a new main event, following Conor McGregor’s injury withdrawal from his fight with Michael Chandler.

Watch the new promo below.

Pereira defeated Prochazka in their first meeting, which took place at UFC 295 this past November. With the win, Pereira captured a vacant light heavyweight title and joined the list of fighters to earn UFC belts in two divisions. He won the middleweight title at UFC 281 with a fifth-round TKO of Israel Adesanya.

A new co-main event has also been booked after an injury forced Jamahal Hill out of a key light heavyweight bout against the surging Carlos Ulberg. Featherweight contenders Brian Ortega and Diego Lopes now co-headline, with Ulberg bumped down one spot on the card into a matchup with veteran Anthony Smith.
