UFC 264: Conor McGregor breaks leg in loss to Dustin Poirier
Poirier said McGregor initially injured the leg earlier in the bout checking a kick. "He fractured it in one of the checks earlier in the fight and it broke on a punch," he said. "When I pointed at it at the beginning of the fight, that's when he did it. I felt something. He was kicking me hard. "Just on the twist of the punch." McGregor was seen yelling at officials, telling them the fight should be called off due to a doctor stoppage, rather than via TKO. He also denies Poirier's claim that an earlier check injured the leg.
