The Ultimate Fighter

The Ultimate Fighter: Team Lesnar vs. Team dos Santos is the thirteenth installment of the Ultimate Fighting Championship produced reality television series The Ultimate Fighter. The UFC and Spike TV held open tryouts on November 4, 2010, in Las Vegas, Nevada. The casting call went out for Welterweight and Middleweight fighters, however, all fighters will be in the welterweight division. All fighters applying and trying out for the show must have at least three professional fights and be at least 21 years of age. Notables who turned up to the tryouts included Strikeforce veterans Karl Amoussou, Andre Galvao, and Zak Cummings, and former TUF contestants Frank Lester and Jeremiah Riggs. It was confirmed during the Fight For The Troops 2 conference call that Brock Lesnar and Junior dos Santos would be the coaches for this season. This season did not feature an elimination round like the two seasons before it, however, the "wild card" selections introduced in season 11 were still featured. The initial cast was 14 fighters rather than the usual 16, 28 or 32 in recent seasons. On May 12, 2011, midway through the airing of the season, Dana White announced that Brock Lesnar pulled out of the coaches' fight due to the return of diverticulitis, forcing Lesnar to withdraw from the bout.
