Why are Weidman and Silva's chins touching at their pre-fight face off? Testing each other's chins? We may never know the answer to this one.
Can Chris Weidman pull off the upset Georges St-Pierre predicted? UFC welterweight champion St-Pierre has been pestered for years about a superfight with Silva, but he wouldn't agree to it yet. Why? Because he thinks Weidman is going to beat Silva. If Weidman pulls it off, he'll be beating one of the best fighters of all time. Can he do it?
Will Frankie Edgar get his fourth straight loss? It's hard to believe that Edgar's record in his last five fights is 1-3-1. Against Charles Oliveira, the one-time lightweight champion is in his first non-title fight since 2009. Will the shorter fight help Edgar find his way back to the win column, or have the losses been too much for Edgar to overcome?
Who will do a better job recovering from a tough loss -- Mark Munoz or Tim Boetsch? In December, Costa Phillippou knocked out Boetsch. Weidman knocked out Munoz last July to earn the title shot he has this weekend. Before their losses, both Boetsch and Munoz were on track for a title shot. They need big wins to get back on the track. Which one will get it?
Will Dave Herman or Gabriel Gonzaga be the heavyweight to get his career back on track? This fight, which will air on the FX prelims, features Gonzaga, who was knocked out in just over a minute in his last fight, and Herman, who lost his last three fights. Wins are needed to keep their career going. Which one will live to fight another day?
