Due to the late notice, the new Ultimate Fighter 18 Finale main event between Nate Diaz and Gray Maynard will be a three-round affair, not five.
UFC officials made the change over the weekend after an injury to UFC lightweight champion Anthony Pettis forced a change. The December UFC on FOX event now gets UFC flyweight champ Demetrious Johnson vs. Joseph Benavidez.
The UFC previously made it known that all main events would be consisted over five rounds, unless a fight is moved into that role on short notice.
Diaz and Maynard will be meeting for the third time, with each holding a win over the other.
