In the main event of UFC 139 this Sat., Nov. 19, 2011, from the HP Pavilion in San Jose, California, "Dangerous" Dan Henderson will make his return to the Octagon to take on former Light Heavyweight Champion Mauricio Rua.

This may or may not be a number one contender bout but the devil is in the details. A win for "Hendo" might actually earn him a middleweight title shot against Anderson Silva, as that's been discussed since his return to the UFC.

However, he's stated he wants his crack at Jon Jones. That may not be possible, of course, thanks to Rashad Evans waiting in the wings. Not to mention, Lyoto Machida already has a date with "Bones" on Dec. 10 at UFC 140. Throw "Shogun" in the mix, as well, if he can emerge victorious.

What a beautiful mess.
