LAS VEGAS (AP) -- Carlos Condit will face UFC welterweight champion Georges St. Pierre at UFC 137 after contender Nick Diaz failed to show up for promotional duties this week.
UFC President Dana White announced the change Wednesday, dropping Diaz from the fight Oct. 29 at the Mandalay Bay Events Center.
St. Pierre's meeting with Diaz, the Strikeforce welterweight champion, has been anticipated by mixed martial arts fans since the UFC bought the Strikeforce promotion earlier this year.
White said Diaz gave no explanation for not attending a UFC news conference Tuesday in St. Pierre's native Canada, and he didn't show up at another event Wednesday in Las Vegas.
St. Pierre is among the most dominant champions in UFC history with nine straight victories.
Condit is a former WEC welterweight champion getting his first UFC title shot.
