UFC 131: Mac Danzig out of Bout with Donald Cerrone; Vagner Rocha Steps in

After suffering an injury during training camp, UFC lightweight Mac Danzig has been forced to withdraw from his bout against former WEC star, Donald Cerrone at UFC 131. The news became official earlier this week, courtesy of MMAJunkie.com.

As a result, UFC newcomer Vagner Rocha will replace Danzig. 

The Brazilian has fought professionally since 2009, competing under multiple organizations such as Bellator Fighting Championship and Strikeforce. Holding a professional record of 6-1-0, Rocha is still relatively young in his mixed martial arts career, but he will certainly want to prove he is a competitor when he is slated to make his Octagon debut in June. 

Cerrone, a former lightweight contender in the WEC, will look to continue his winning streak in the UFC. In his debut at UFC 126, Cerrone picked up a victory over Paul Kelly via rear naked choke, in addition to receiving "Submission of the Night" honours. Cerrone was one of the top lightweight contenders in the WEC and he will look to make a similar impression in the UFC lightweight division. 

This is one of the few changes the UFC 131 card has had to endure, so far. 

UFC heavyweight, Shane Carwin, who will headline against Junior dos Santos, replaced dos Santos' original opponent, Brock Lesnar, after the former UFC heavyweight champion came down with diverticulitis again. 

UFC 131 will take place on June 11, live from the Rogers Arena in Vancouver, British Columbia, Canada.
