UFC middleweight champion Luke Rockhold is in need of a new opponent for UFC 199 after Chris Weidman was forced to pull out of their scheduled rematch due to injury. The event is set to take place in just over two weeks.

Following Weidman’s withdrawal, Rockhold posted via Instagram: “I might lose my hair but I will never lose my work ethic. No matter who, no matter when, no matter where. I’ll be ready.”

Though no replacement has been announced for Rockhold, a former opponent of the champ’s, Michael Bisping, has already offered to step up.

Bisping defeated former UFC 185lb champ and all-time great Anderson Silva via decision at UFC Fight Night 84 in February. The win makes him one of the most legitimate title contenders in the division, alongside Ronaldo ‘Jacare’ Souza who defeated Vitor Belfort this past weekend at UFC 198. Rockhold holds wins over both Bisping and Jacare, which adds an extra element of interest to both potential contests.

UFC 199 takes place June 4th at The Forum in Inglewood, California.
