It's a matchup that's going to pin one of the heaviest hitters of all time against quite possibly the most defensively potent light heavyweight in UFC history.
Coming in to this fight, both top contenders have something to prove. Henderson needs to regain divisional momentum after pulling out of UFC 151, which forced the UFC to cancel an event for the first time in promotional history.

So before two fantastically talented women grace the Octagon for the very first time, tune in and watch two of the most relevant fighters go toe-to-toe. Here's how the fight breaks down.
