The Joe Duffy v Conor McGregor rematch dream has hit a stumbling block.
Duffy handed The Notorious his last defeat in MMA over five years ago during their Cage Warriors days, and now Duffy has tasted defeat himself for the first time in UFC after he was handily beaten over three rounds against Dustin Poirier.
The Irishman was a favourite according to the Vegas odds, but was stunned early on when a Poirier combination earned the respect of the former professional boxer.
A decisive second round for Poirier earned him a victory on points, although many suspect that if Duffy had been given just a few more seconds he could have gained a submission with a tight triangle hold – the same move he used to beat McGregor after just 38 seconds back in 2010.
