Former WEC featherweight champion Urijah Faber will be out to November according to a report by Sherdog.com.

In July, Faber, arguably the promotion's most popular star, withdrew from his bantamweight debut bout against Takeya Mizugaki, which was scheduled for WEC 50 "Cruz vs. Benavidez" on Aug. 18 at the Palms Hotel and Casino in Las Vegas. Faber, suffered a knee injury in training that didn't require surgery, said his MMA Inc. manager Mike Roberts.

The 31-year-old California native was tentatively expected back in September to face Mizugaki in the re-scheduled bout. However, sources close to both fighters' camps indicated that the fight could be pushed to November or even December on account of Faber's rehabilitation.

Faber (23-4) has lost three of his last five fights (with all three losses being title fights). His most recent loss to Jose Aldo in April led to his decision to drop to the bantamweight division.

Usually, Faber being out could be considered a big blow to the WEC, but in this instance, the promotion's cards in August and September have enough star power to more than likely hold up without Faber. His return will bring a much-needed boost to whatever show he's on.
