LAS VEGAS – MMA legend and now UFC Hall of Famer Wanderlei Silva is content with his combat sports career, but he would get back into the ring to settle the score with a couple of select opponents. Silva, 48, has been one half of a number of historic rivalries, but two in particular stand out for him that could still produce another fight if the other sides agree to throw down again. In fact, Silva would like to mix it up in the boxing ring with his final two MMA opponents, Chael Sonnen and Quinton “Rampage” Jackson.
