Former PRIDE welterweight and middleweight champion Dan Henderson will take on rising star Daniel Cormier. They are currently ranked as the No. 6 and No. 4 light heavyweights, respectively.
The co-main event should draw significant interest. Both men have storylines against current champion Jon Jones, but Alexander Gustafsson could throw a wrench into those plans should he defeat the champion in their rematch later this year.
Two high-level wrestlers with big power enter the Octagon Saturday with a lot on the line. It is an intriguing stylistic matchup, but Cormier is the heavy favorite coming in. How will the fight play out, and who will earn the next title shot?
This is your head-to-toe breakdown of the co-main event heading into UFC 173 this weekend.
