Mixed martial arts fans have enjoyed an embarrassment of riches lately, and UFC 94 “St. Pierre vs. Penn 2” serves as the seven-layer chocolate mousse cake at the end of a five-course feast. Besides the epic headliner, the event will have plenty of backup when it’s beamed into our brains this Saturday from the MGM Grand Garden Arena in Las Vegas.

Whether it’s the light heavyweight tilt between undefeated Brazilians Lyoto Machida and Thiago Silva or the return of UFC regulars Karo Parisyan and Stephan Bonnar, there’s something for everyone on this main card. Even lightweight aficionados get a bout to call their own, as “The Ultimate Fighter” season five winner Nate Diaz takes on all-around man’s man Clay Guida.

Of course, the fight that has all the fans on edge is the rematch between UFC welterweight champion Georges St. Pierre and UFC lightweight titleholder B.J. Penn. Pound-for-pound esteem and long-term legacies are up for grabs in this one.
