From Josh Gross:
Priority No. 1, according to sources in his camp, remains whether or not to lodge a formal complaint with the Nevada State Athletic Commission alleging Georges St. Pierre's corner knowingly and illegally used Vaseline on the UFC welterweight champion's body to gain an unfair advantage Saturday night at the MGM Grand Garden Arena.
Should Penn decide to move forward and attack the integrity of St. Pierre and his camp, chances are the Hawaiian will want to fight again. That, surprisingly, is not an automatic. Though the answer seems obvious considering Penn, who is only 30, appears perfectly capable of carving himself a meaningful legacy at 155, no one close to "The Prodigy" knows for certain if he'll return.
"Before we got to Vegas we were talking," Penn's chief trainer, Rudy Valentino, said Sunday evening after returning to Hilo. With a win over St. Pierre "he wanted this to be his last fight."
As much of a bummer as this would be it doesn't surprise me. Its been very clear for a long time that B.J. Penn marches to his own drummer and that he is bored fighting at 155lbs. Personally I'd love to see him continue to fight but if he hangs up the gloves all I can say is "Aloha B.J., thanks for all the great fights."
