World Extreme Cagefighting featherweight champion Urijah Faber knows he has bigger things to worry about - such as Sunday's World Extreme Cagefighting 34: Faber vs Pulver main event fight with Jens Pulver - but the 29-year-old fighter says he eventually wants to avenge his only career loss.

Faber won his first eight professional fights before suffering a third-round TKO loss to current UFC lightweight Tyson Griffin at a September 2005 Gladiator Challenge event.

During a special podcast session coordinated by VERSUS, Faber said that he wants a second chance at beating Griffin, and he's willing to move up a weight class to get it.

"I'd definitely like to avenge the loss, of course," said Faber, who secured the WEC's 145-pound title in March 2006. "It's my only blemish. At this time, it's something that could happen in the future. We're both pretty young in the sport."

Faber and Griffin compete in different organizations, but they're both under the Zuffa LLC umbrella. However, UFC president Dana White has long maintained that the two organizations would operate independently. A few UFC fighters have been sent to the WEC, but there's been no talk of a co-promoted show or WEC vs. UFC "superfights" anytime in the future.

For what it's worth, Faber said he's willing to jump up a weight class if means getting Griffin as an opponent. The UFC doesn't currently have a 145-pound weight class, and Griffin fights as a 155-pounder in the UFC.

"I wouldn't have a problem going up to 155," he said. "We were actually supposed to do it one time before [Griffin] went into the UFC."

Griffin, meanwhile, suffered his only career loss to Frank Edgar in February 2007. He's won three straight fights since then and next meets Marcus Aurelio in July at UFC 86: Jackson vs Griffin.
