Anthony Smith highly doubts that Dustin Poirier would turn down a fourth fight with Conor McGregor . Poirier (29-7 MMA, 21-6 UFC) and McGregor (22-6 MMA, 10-4 UFC) have fought three times, with Poirier winning their past two meetings by TKO. But with McGregor breaking his leg in the first round of their trilogy bout in July 2021, the Irish superstar says they have unfinished business. Although Poirier was initially dismissive of the idea of a fourth fight , a recent back-and-forth between the two appeared to suggest otherwise. Either way, Smith doesn’t see why Poirier wouldn’t accept a fourth fight.
