MMAJunkie.com has the scoop on the latest of Shogun's many knee operations:

Newly minted UFC light heavyweight champion Mauricio "Shogun" Rua's first title defense likely will be delayed due to a recent knee surgery.

Rua (19-4 MMA, 3-2 UFC), who knocked out Lyoto Machida at UFC 113 to earn the 205-pound title, was expected to meet Rashad Evans later this year.

With Rua's window of recovery, UFC president Dana White is unsure when the Brazilian champ will fight again.

"He just got out of the hospital; it was a successful surgery," White said. "He had the surgery in [Los Angeles], and he's going to be doing all his therapy in (Las) Vegas.

"So he'll be in Vegas for the next five weeks."

ESPN's Franklin McNeil reported Shogun had a knee injury prior to UFC 113, but White said Shogun sustained the injury during the fight.
