Muscle Pharm and Fight to Win Promotions put on a star-studded grappling event to raise awareness and money for children's cancer research back in August. Submit Cancer was a wild success which raised over $63,000 to benefit the local Denver-area children's hospital.

The event featured an auction, autograph signings, free food from local food trucks, and, of course, some of the biggest names in not only jiu-jitsu but also MMA, as well. Lyoto Machida, Neil Magny, Jake Shields and the consensus No. 1 grappler Marcus "Buchecha" Almeida all showed up to compete for the cause.

On Tuesday, Muscle Pharm CEO Ryan Drexler, along with Drew Dober, Matt Brown, Garry Tonon, Gordon Ryan and a number of other famous fighters, delivered the check directly to the Children's Hospital Colorado Foundation.
