Following his win at UFC 137 on Saturday night Nick Diaz got on the mic and claimed that Georges St.Pierre, who watched his fight with BJ Penn from cage-side, was faking his recent knee injury.

Now his manager Cesar Gracie has added fuel to that fire by telling the media after the event that he saw the welterweight champion running despite his supposed injury.

“He ran past me earlier. He literally ran past me. I don’t know the guy personally. I’m gonna tell you guys something right now … Nick Diaz missed a press conference and he’s here and fought. The guy that went to the press conference didn’t fight. That’s all I got to say about it.”

Meanwhile a member of the media also claimed that Gracie also jumped down from the cage while cornering the debuting Francis Carmont at the event.

For his part GSP is still adamant that he does have a legitimate injury, telling MMAfighting’s Ariel Helwani just hours before the main event that it’s lateral movement that is causing him the most pain.

While Diaz inferred that the reason the Canadian had faked the injury was because he was “scared”, what we do know for certain is that after hearing those remarks the champion went straight to UFC president Dana White and asked him to make the fight between the two ASAP.

White granted him that wish, and the two will now be able to settle their differences once and for all in the Octagon on Superbowl weekend in February.
