Hikaru Sato
After the bout against Nogueira and the acquisition of PRIDE by the UFC, Barnett did not participate in any MMA events in 2007, except one Pancrase match against Hikaru Sato, which was held under catch wrestling rules on Dec. 22. Barnett did not follow many other PRIDE veterans to the UFC because he desired to join an organization that included the top Heavyweight fighter in the world, Fedor Emelianenko. In 2008, Barnett joined the newly organized MMA promotion, Sengoku, and fought in consecutive main events at Sengoku 1 and Sengoku 2, submitting Hidehiko Yoshida with a heel hook in the third round, and defeating Jeff Monson by unanimous decision.
