Ronda is not fighting the #2 or 3 in her division so not much of a fight there. Hendo still has some fight left in him so Machida will have his hands full. Also,Will the rounds be the standard three 5 min rounds or five 5 min rounds? I only ask because Hendo is pretty old and he was visibly tired by the third round in his fight with Shogun. If it is 3 rounds then I say Hendo.
Probably a solid enough reason to make this a co-main event. Henderson knows he's not got the cardio for a 5 rounder.
