Former UFC light heavyweight champ Forrest Griffen, recently went under the knife to repair a right-shoulder injury that the fighter acquired during training, and the same injury that forced him out of UFC 114.

Griffin’s trainer, Jimmy Gifford reported to The Las Vegas Sun that the procedure was “nothing crazy.”

“He’ll start physical therapy in six weeks and be on the shelf for 12 weeks,” said Gifford. “We’re not sure on a return, but October would be a good guess. Maybe late September.”

Gifford went on to say that Griffin would be willing to not return until December, in hopes that his return would be in the US as to avoid the inconvenience  of over-seas traveling.

“The UFC usually does a November show in the U.S. and a December show in Vegas,” Gifford said. “Rather than go oversees, we’ll maybe do a November or December date. He can’t stand the travel and he loves fighting in Las Vegas.”

Since Griffin was forced out of the bout, Antonio Rogerio Nogueira will instead be facing Jason Brilz at UFC 114 on May 29th.
