In a thrilling UFC 303 event in Las Vegas, Alex Pereira successfully defended his light heavyweight title with a second-round knockout of Jiri Prochazka. The rematch saw Pereira deliver a devastating head kick followed by ground strikes, continuing his dominance in the division. The event was marked by last-minute changes, including Dan Ige stepping in for an ill Brian Ortega to fight Diego Lopes, who won by unanimous decision. Ian Machado Garry maintained his undefeated streak by out-grappling Michael 'Venom' Page, securing a 29-28 victory from all three judges. The originally scheduled headliner featuring Conor McGregor was canceled due to a broken toe, prompting Pereira and Prochazka to step in with only two weeks' notice.
