Dr. ElAttrache says my surgery (ACL patellar tendon autograft) was huge success! Ligament very strong. Tks for support!
Currently, there is no timetable for a potential return to the Ultimate Fighting Championship (UFC); however, it's possible that we won't see the promotion's welterweight champion back inside the Octagon for at least 10 months or more.
In the meantime, Carlos Condit and Nick Diaz will battle for the interim 170-pound belt on SuperBowl weekend to keep the division moving. Upon his return, St. Pierre is expected to face the winner of that bout, or the current interim champion, if the Condit-Diaz winner is no longer in the top spot.
St. Pierre was bit bad by the injury bug recently -- this latest setback was his second in a span of two months, the first of which forced him out of a title fight against the "Natural Born Killer" at UFC 137 back in October.
