The injury bug doesn't affect mixed martial arts only.

Felipe Costa black belt and 2009 ADCC bronze medalist Ryan Hall is out of his jiu-jitsu match with Ricardo Miller black belt Bill Cooper at Metamoris II. Sources close to the situation tell MMA Fighting Hall suffered a shoulder injury in training and has officially withdrawn from the event.

The organization has not made the news official, nor is there word on whether the Paragon Jiu-Jitsu representative and Strikeforce veteran in Cooper will face another competitor.

Metamoris is a jiu-jitsu competition comprised entirely of grappling superfights, both with and without the use of a gi. All matches are 20 minutes in length with no points awarded for techniques. Bouts can only be won by submission or in the event where no submission takes place, a panel of judges will determine a winner.

Metamoris II takes place at the Pauley Pavilion in Los Angeles, California on June 9th. The event is headlined by a match between former DREAM and current ONE FC lightweight champion Shinya Aoki and Rickson Gracie black belt Kron Gracie.
