In the main event, longtime UFC Lightweight champion Ben Henderson returns to the Octagon in an attempt to "rid himself of the Pettis stain" as he defends his 155-pound title for the fourth time against Anthony Pettis, the same man who took his World Extreme Cagefighting (WEC) Lightweight strap three years ago.
The night's co-main event will see two former Heavyweight champions finally duke it out as Josh Barnett returns to the Octagon after an 11-year hiatus to take on longtime veteran Frank Mir who is looking to rebound from two consecutive defeats.
Shortly after the official UFC 164 weigh in event (watch highlights here), UFC Light Heavyweight contender Chael Sonnen and his fellow FOX analyst -- and former three-time title contender -- Kenny Florian, broke down the 155-pound championship contest that is set to serve as this weekend's main event from "Brew City."
That prediction and much more in the video above.
