UFC 251, scheduled for July 11 at UFC's "Fight Island" facility on Yas Island, Abu Dhabi, will be without one of its main event fighters.
Gilbert Burns has tested positive for coronavirus and is being scratched from the event, according to Mike Bohn of MMA Junkie. He was scheduled to fight welterweight champion Kamaru Usman.
Bohn reports that the fight is expected to be rescheduled for a later date. Burns had been training in Florida and traveled to Las Vegas for testing. His brother and cornerman, Herbert Burns, and coach Greg Jones have also reportedly tested positive.
