A potentially big welterweight division fight has been added to UFC On Fox IX as Matt Brown battles Carlos Condit. Brown will enter the fight riding a six fight winning streak, most notably defeating Mike Pyle at UFC Ultimate Fight Night 26. Condit has only won one of his last three in the UFC, with that win coming over Martin Kampmann at UFC Ultimate Fight Night 27. UFC On Fox IX takes place on December 14th from the Sleep Train Arena in Sacramento, California with Anthony Pettis and Josh Thomson headlining.
