Georges St-Pierre's training camp is claiming that the champion was injured during his UFC 158 title defense against Nick Diaz and may be out six months.
That's the latest word on "Rush" from Tristar Gym head trainer Firas Zahabi, who told TVA Sports and MMA Fighting that GSP went five rounds against Diaz while suffering from an Achilles injury on the same leg that was hampered by a torn ACL last year.
Moreover, Zahabi suggests that had GSP's injury worsened during the match, the outcome of that fight may have been different:
"I was worried it would tear during the fight," Zahabi told MMAFighting.com. "We had to cut his last sparring [session] short due to his injury. He had a week to rest it and then the fight."
"He wants to take a couple of months off because his two fights were very close to each other," he said, "and he wants to enjoy the summer. We haven't talked to the UFC yet, so we don't know what their plans are for Georges yet."
According to MMA Fighting, Zahabi doesn't want St-Pierre to return to the Octagon for six months, which would see GSP away from competition until August or September 2013.
St-Pierre previously suffered a potentially career-ending ACL tear in December 2011 while training for a planned UFC 143 bout versus Diaz.
Could GSP have finished Diaz healthy?
That set in motion a roundabout title situation for the UFC welterweight division that saw Diaz face Condit for an interim championship instead where Diaz lost by a controversial decision.
Diaz also tested positive for marijuana metabolites afterward, leading to a one-year suspension and a legal battle with the Nevada State Athletic Commission.
St-Pierre later returned to successfully unify the title against Condit at UFC 154 in a bloody war before returning to Montreal to steamroll Diaz en route to a heavily one-sided decision victory at UFC 158.
That fight marked Diaz's first back-to-back losses since a previous UFC stint in 2006, where the Stocktonian dropped a pair of fights to Sean Sherk and former UFC fighter Joe Riggs—whom Diaz infamously confronted afterward in a fight at a Las Vegas medical center (via MiddleEasy).
