Former UFC light-heavyweight champion Mauricio "Shogun" Rua has been training his boxing with famed boxing trainer of Manny Pacquiao, Freddie Roach. This comes in preparation for Shogun's fight with Chael Sonnen on August 17th at UFC on Fox Sports 1. "I learned some tips that I will practice while training for my next fight", says Rua, who main events the card with Sonnen in Boston. "We worked a lot on my jab and my left hand to find my distance so I can feel comfortable while fighting."
