Manager: Chael Sonnen Not Fighting Wanderlei Silva at UFC 153

Chael Sonnen will not be stepping in on short notice to fight at UFC 153.

Sonnen's manager Mike Roberts refuted a Fighters Only report on Wednesday that Sonnen vs. Wanderlei Silva was a possible main event replacement for the injury-plagued UFC 153 card.

According to Roberts, Sonnen has not been offered a fight at UFC 153, and he is still scheduled to fight Forrest Griffin at UFC 155 on Dec. 29.

"[Wanderlei] Silva's not an option," Roberts added.

UFC 153 lost its main event and co-main event on Tuesday after Jose Aldo pulled out of his featherweight title fight against Frankie Edgar due to a foot injury and Rampage Jackson withdrew from his fight against Glover Teixeira due to an elbow injury.

UFC 153 is scheduled to take place on Oct. 13 at HSBC Arena in Rio de Janeiro, Brazil.
