The Irish fighter suffers horrific injury in another crushing defeat to the American in a Las Vegas showdown.

Conor McGregor suffered a broken leg in another crushing defeat to Dustin Poirier at the T-Mobile Arena in Las Vegas, with the fight stopped by doctors at the end of the first round. It was an anti-climactic finish to an action-packed round in the fight on Saturday, as both fighters were still trying to land McGregor stumbled backwards, trapping his foot under himself and breaking his leg. Medics were immediately called into the octagon and it was clear that McGregor could not continue, prompting referee Herb Dean to declare a stop to the bout on the instructions of the doctor.
