LAS VEGAS -- Dustin Poirier now owns two victories over the biggest star in the history of mixed martial arts. This one, though, didn't end in the cleanest way.
Poirier hit Conor McGregor with a combination at the end of the first round of Saturday night's highly anticipated main event at UFC 264. McGregor went to plant his left foot -- and his leg buckled, sending him to the mat. Poirier followed up with punches on the ground as time expired.
With McGregor's leg clearly hurt, referee Herb Dean called the bout.
