The UFC heavyweight will take on Ryron Gracie, son of UFC co-founder Rorion Gracie, in an openweight grappling match Saturday, Metamoris announced Wednesday. Barnett's original opponent Roberto "Cyborg" Abreu pulled out due to an injury.
Barnett is the organization's heavyweight champion. His bout with Abreu was slated to be the main event. Retired UFC star Chael Sonnen will meet Renato Sobral in the co-headliner. Metamoris will air live on internet pay-per-view Saturday, but will not be open to the public. Also on the card, UFC veteran Joe Lauzon will take on Dillon Danis.
