Tatame is reporting that Antonio "Bigfoot" Silva has gone under the knife. His manager told the site that it was an arthroscopic surgery to correct an injury suffered in his Strikeforce Heavyweight Grand Prix bout with Daniel Cormier. Silva lost that bout via knockout, his first loss since dropping a decision to Fabricio Werdum in 2009.
Prior to dropping the fight to Cormier, Silva was at the high point of his career after dominating Fedor Emelianenko in the first round of the tournament. It was the worst beating of Fedor's career and one that established Bigfoot as a force at heavyweight.
It's expected that Silva will be able to return to training in 6 weeks so he will hopefully be able to make a return to either the Strikeforce or UFC cage sometime fairly early in 2012. With the way the UFC has been picking top fighters off from Strikeforce it's entirely possible we see him come to the UFC to beef up the heavyweight roster.
