Munoz was next rumored to be set to fight former WEC light-heavyweight champion Brian Stann for a number-one contender slot. Instead, Stann signed to face Chael Sonnen and left Munoz without an opponent for the foreseeable future.
Munoz next faced veteran Chris Leben in the first five-round non-title fight in UFC history. Munoz bloodied up Leben's left eye, forcing the doctor stoppage between the second and third rounds. Leben was quoted as saying: "I can't see shit." With the victory, Munoz was rumored to get the next title shot against his friend, UFC middleweight champion Anderson Silva. Munoz heavily supported the idea.
Beginning of the EndEdit
After recovering, Munoz was next heavily rumored to face undefeated wrestling prospect Chris Weidman. He did face Weidman, losing via a brutal second round elbow knockout.
After a long, long layoff Munoz finally returned in March 2013 to sign to fight Tim Boetsch on the Fourth of July weekend, 2013. Munoz defeated Boetsch via an entertaining unanimous decision.
Munoz next signed to fight contender Michael Bisping in Bisping's native England. Bisping was injured in late September 2013 and replaced by former UFC light-heavyweight champion and middleweight newcomer Lyoto Machida. Machida and Munoz had been training together just days before at Black House.
“It took me by surprise that all of the sudden I’m fighting Lyoto Machida. Total different fight, total different approach and preparation, but you literally have to roll with the punches," Munoz said. "We were training two days before, and all of the sudden, we’re slated to fight each other. We had spoken to each other, and we’re like, ‘We’ll put 25 minutes aside and the winner buys dinner.’ Lyoto is very strategic in what he does. I’m going to be able to corral him and restrict him in his space and not allow to use the whole cage. I’ll be in shape to go five rounds."
Machida unfortunately knocked Munoz out in the first round with a highlight reel kick to the head, helping him up afterwards. The pair embraced in a great show of sportsmanship and it was clear to any watching that Munoz would be back stronger than ever.
Except He Wouldn't BeEdit
Munoz next signed to fight in May 2014 at the UFC's first event in Berlin against Machida's next victim, former Strikeforce light-heavyweight champion Gegard Mousasi. Mousasi defeated Munoz via a first round rear naked choke submission.
