The Ultimate Fighting Championship has a little under a day to find a suitable replacement.
First broken by reporter Laerte Viana on Thursday night, Mohammed Usman (11-4) has sustained an undisclosed injury and has been ejected from his heavyweight match with Valter Walker (14-1). It is unclear at this time if the organization will be able to snag a local heavyweight to face Walker by the weigh-ins on Friday. If not, the promotion has yet to indicate if it will preserve the match or relocate these two fighters to other bouts down the line.
