Confirmed - UFC 131 Brock Lesnar vs. Dos Santos

The Ultimate Fighting Championship expects its next show in British Columbia to decide the first challenger for heavyweight champion Cain Velasquez.

Junior dos Santos vs. former titleholder Brock Lesnar will take place June 11 in Vancouver at UFC 131, the promotion announced Thursday on its Ultimate Insider online program. The fight between opposing coaches on the upcoming season of The Ultimate Fighter will decide the No. 1 contender for Velasquez.

Velasquez was supposed to face dos Santos in the spring, but the champion recently underwent surgery for a partially torn rotator cuff that will keep him shelved until summer at the earliest. Dos Santos, who hasn't fought since August, didn't want to wait that long.

Lesnar's last fight was the title loss in October, when Velasquez battered him for a technical knockout in the first round. Dos Santos uses a different approach.

The game plan for Velasquez, an elite wrestler, revolved around scrambling quickly to his feet after Lesnar's takedowns and following up with quick punches thrown from angles. But dos Santos prefers to stuff takedowns and move straight ahead to throw uppercuts and hooks from short range, always looking for a knockout.

UFC has used most seasons of its reality show to promote coaching rivalries that culminate with a fight on pay-per-view. TUF 13 is scheduled to start airing later this month.
