On December 5, 2009, Jones fought fellow light heavyweight prospect Matt Hamill at The Ultimate Fighter: Heavyweights Finale. Jones used his wrestling to dominate Hamill, dislocating Hamill's shoulder with a takedown, and battering him with strikes. However Jones would be disqualified for the use of illegal 12-6 elbows. The Unified Rules of Mixed Martial Arts prohibited downward elbow strikes, and Jones was initially only penalized a point from the round. However Hamill was unable to continue due to his dislocated shoulder. Consequently, the replay simulation was reviewed, and showed that Jones's elbows further damaged Hamill's already bloody and lacerated nose. This marked the first time that Nevada has used its recently enacted instant replay rule, in which the referee's decision was supported by the commission, which utilized a slow-motion replay to review the elbows. UFC president Dana White was aggrieved that referee Steve Mazagatti ruled the bout as a loss for Jones, saying that it should have been a no contest. In 2019, White said he was still attempting to have the result overturned to a no contest by the Nevada State Athletic Commission.
