LAS VEGAS - Saturday night's UFC 137 event may very well have marked the final fights in the careers of two MMA legends.
That said, UFC president Dana White isn't 100 percent certain both Mirko
"Cro Cop" Filipovic and B.J. Penn have entered the cage for the final time.
"B.J. is a warrior," White said. "What happened to him tonight has never
happened to him in his entire career. What he's thinking tonight he
might not think eight weeks from now."
