Conor McGregor was visibly upset after his fighter Nate Jennerman was knocked out in less than 10 seconds on The Ultimate Fighter.
Former two-weight UFC champion McGregor, 34, is coaching alongside his rival Michael Chandler on season 31 of the reality TV show ahead of their fight later this year. The inaugural episode of this year's The Ultimate Fighter aired on Tuesday and it didn't go as planned for Team McGregor as Jennerman was stopped by Roosevelt Roberts in the first fight of the season.
Jennerman was stunned by a big right hand just three seconds into the bout and Roberts, a UFC veteran who served a three-year stint in the promotion, went straight for the finish. Roberts landed the same shot just seconds later, dropping Jennerman and finishing the fight with some follow-up hammer-fists. McGregor could then be seen slapping his hands together in frustration whilst watching the bout from cageside.
