Coaches involvement With the exception of seasons 2, 4, 11, 13, 15, 16, 22 and season 1 of TUF: Brazil the coaches fought each other after the conclusion of the show. Season 2 featured Rich Franklin and Matt Hughes, who were in different weight categories, eliminating the possibility for a post-season fight. Season 4 saw multiple guest coaches take the lead, differing from other seasons with two clearly designated coaches. Season 22 did not feature a fight between coaches Conor McGregor and Urijah Faber since McGregor was the UFC Interim Featherweight Champion and had an automatic title unification with Featherweight Champion José Aldo next. As such, these seasons did not feature their respective coaches in competition. Season 11 coaches Tito Ortiz and Chuck Liddell's fight was cancelled due to Ortiz's need for neck fusion surgery. Season 13 saw the fight between Brock Lesnar and Junior dos Santos cancelled after Lesnar was diagnosed with his second bout of diverticulitis. 2012 saw the cancellation of a bout between season 15 coaches Dominick Cruz and Urijah Faber, due to a torn ACL for Cruz. In addition, the expected fight between the TUF: Brazil coaches Vitor Belfort and Wanderlei Silva did not occur after Belfort sustained a broken hand while preparing for the fight. Season 16 was supposed to feature a fight between coaches Roy Nelson and Shane Carwin, though this was also cancelled after Carwin suffered a knee injury. In addition to the seasons which did not feature post-season fights between the coaches, several seasons have been impacted, forcing postponements. Due to injuries to the season six coaches Matt Serra and Matt Hughes, their fight was postponed. Serra suffered a herniated disc in his lower back
