Conor McGregor has been warned he will likely have to be drug-tested for six months before he can return to action.
McGregor has not fought since he broke his leg in his trilogy fight with Dustin Poirier last summer. He had planned to fight this year but has struggled to recover completely from the injury.
He has also removed himself from the USADA drug-testing pool which has thrown his return date into doubt. Fighters are required to be in the pool for six months before they can resume their careers, but McGregor insists he will be given an exemption to allow him to test just twice before making a comeback.
