According to Conor McGregor, the Irishman re-injured his knee so bad before the Mendes fight that he couldn't even stand up at times.
It was supposed to be one of the biggest fights in UFC history, the featherweight championship bout between Jose Aldo and Conor McGregor at UFC 189. But less than two weeks before the fight, Aldo pulled out with fractured rib, that he suffered during a training session, what resulted in a McGregor trash-talking frenzy. Chad Mendes jumped in on ten days notice to save the day, in what has now been scheduled as an interim-championship bout, but lost via second-round T.
