These two heavyweights went at it after a scrum in the corner ended with a stick to Primeau's throat. He retaliated with an elbow to McAllister and before long, the gloves were off and punches were flying. While Primeau took a couple hard shots to the jaw, McAllister had to be taken to the trainer's room to have his hand X-rayed. And the best part of the battle -- it was all captured on YouTube.
