UFC welterweight champion Georges St-Pierre has cleared one hurdle on his comeback trail.
The injured fighter had successful knee surgery on Tuesday in Los Angeles, he recently tweeted.
A torn ACL and damaged meniscus recently forced St-Pierre out of a February UFC 143 title fight with Nick Diaz. Carlos Condit and Diaz now will fight for an interim title while St-Pierre’s on the sidelines for six to 10 months.
