The Brazilian Thiago Pitbull would face Matt Brown in the first edition of the UFC On FOX Sports series, but a new injury tormented him again. The North American Mike pyle will replace the Ceará native in the fight.

Pitbull hasn't fought since March 2012, when he was submitted by Martin Kampmann in Australia. He would return in July, at UFC 149, but was injured and had to withdraw from his commitment. After recovering, Thiago intended to make a triumphant return at the Boston event and will now have to undergo another rehabilitation.

The new clash will pit two fighters with beautiful recent campaigns in the welterweight category. Mike pyle won the last four engagements, knocking out Josh Neer, Richard Funch and James Head, closing the series with a decision victory over Rick Story. Brown, on the other hand, reinvented himself after being threatened with dismissal. He has gone through his last five opponents, knocking out Mike Swick, Jordan Mein, Chris Cope and Luis Beição, as well as controlling Stephen Thompson in triumph by decision.

The first event to be broadcast on the North American channel FOX Sports 1 will take place on August 17th, the day the broadcaster debuts in the United States. The main fight will be in charge of Mauricio Shogun e Chael Sonnen, in the light heavyweight division.
