Metamoris 6 will feature a new, open-weight main event after a late injury felled grappling wizard Roberto Abreu, who was expected to tangle with Ultimate Fighting Championship (UFC) heavyweight Josh Barnett. "Cyborg" separated his rib in training and will be replaced by Ryron Gracie.
Unfortunately due to a rib injury, I won't be able to fight this weekend at Metamoris. It has been a tough decision to make. I was fully committed to my training and very motivated with the chance of defending the flag of BJJ and taking the title from Josh Barnett, but my trainers and doctors advise me not to fight since I wouldn't be able to perform, risking my health and jeopardizing my career.
