Jason Jackson It was on the set of “The Ultimate Fighter 21” that Jason Jackson ’s career took a turn. Seemingly on his way to a first-round TKO win over Michael Graves in the first round of the reality show’s tournament, Jackson, a member of the Blackzilians vying against American Top Team, gave up a takedown and wound up submitted in short order. He was not asked to compete on the undercard of the show’s live finale like other cast members.
