The 38-year-old veteran hasn't slipped quietly into retirement though, even if we haven't heard much from him. Sherk revealed today on his Twitter account that he'll be back in the Octagon before 2013 -- but that he won't be settling for just any lightweight opponent.
"I will be coming back before the years end but I need a good fight not some chump who needs some fame!" Sherk posted.
The Muscle Shark beat Kenny Florian to win the vacant UFC lightweight belt back at UFC 64 in 2006 and then defended it successfully against the now-incarcerated Hermes Franca. Following that fight, Sherk tested positive for a banned substance and was stripped of the belt.
Since then, Sherk has split his Octagon appearances, balancing losses to BJ Penn and Frankie Edgar with wins over Tyson Griffin and Evan Dunham. He most recently appeared in action against Dunham, taking a controversial split decision over Dunham at UFC 119.
