The UFC has replaced the highly anticipated fight between Conor McGregor and Michael Chandler that was supposed to headline UFC 303 in Las Vegas on June 29.

It would have been McGregor's first fight since breaking his leg in a loss to Dustin Poirier in 2021 and Chandler's first time back in the Octagon since losing to Poirier in 2022. McGregor opened as a -112 favorite, but those odds flipped toward Chandler before the fight was eventually called off.

Instead, Alex Pereira vs. Jiří Prochazka will headline the event in a light heavyweight title fight.

Rumors had been swirling since early June that the fight might be in jeopardy. Here's a brief timeline of events that led up to the biggest fight of the year being called off.
