It's a lightweight battle that helps kick off the main card. Fabricio Camoes is a mean submission machine, with seven submission wins to his pro career. Yet, he faces a well-rounded Jim Miller, who is hungry for a victory. But, Camoes says he's undaunted and ready to bring it in the Octagon. Both men are in it to prove a point -- see who takes the W at UFC 168: Weidman vs Silva 2, live on Pay-Per-View, Saturday, December 28, live from the MGM Grand Garden Arena.
