Key fighters: Michael Graves, Hayder Hassan, Sabah Homasi, Vicente Luque, Kamaru Usman.

Cool anecdotes: Episode 11 features one of the most epic cold shoulders in TUF history. Blackzilians coach Glenn Robinson was irate at the decision to not stop the Jason Jackson-Michael Graves fight in that episode and berated the officials cage-side before calming down. He later waits outside for the referee to discuss further, but the ref leaves without saying anything to Robinson. All fights took place at the two gyms in Florida instead of a Vegas-housed effort.
