Conor McGregor and Max Holloway had to be separated by Dana White and security during their UFC 329 staredown Thursday night, after McGregor tore off Holloway’s sunglasses and the two went forehead to forehead. The confrontation raises the stakes ahead of Saturday’s rematch at T-Mobile Arena, McGregor’s first UFC fight in five years and a sequel to their 2013 bout, which McGregor won by decision. White has called it the promotion’s biggest gate ever, and fans reacted to the staredown with a mix of hype and skepticism.
