MMA is governed by the Unified Rules. The Ultimate Fighter is governed by Dana White.
The UFC president is consistent in some ways. He’s sympathetic to those who’ve been injured. He’s not sympathetic to people who quit in any sense he can define.
Trouble at home? Depends. Abdel Medjedoub got a trip home, an accommodation usually reserved for those who’ve had a death in the family, to talk to his fuming wife. Noah Inhofer couldn’t even get a phone call and chose to leave TUF and the UFC’s good graces forever.
