Conor McGregor appeared to break a bone at the end of Round 1.

Conor McGregor lost his rematch against Dustin Poirier after a bizarre end to the first round in which McGregor appeared to break either his lower left leg or his ankle. As McGregor and Poirier swung at each other, McGregor stumbled backward and broke a bone without Poirier hitting him.
In a post-fight interview, Poirier said that he believed McGregor fractured his ankle earlier in the fight — when Poirier successfully defended a kick — and that the break was completed when McGregor stumbled backward. McGregor, using unprintable language, disagreed.
“This guy is a dirtbag, man,” Poirier said about McGregor, angry about prefight trash talk that he believed repeatedly crossed the line.
Before the bizarre ending, the fight was a barnburner. McGregor and Poirier came out swinging and kicking, familiar with each other from two previous matchups. Poirier scored a mid-round takedown, and kept McGregor on the ground for most of the rest of the round, landing a flurry of elbows to McGregor’s face that left his ear bloody.
