Maybe Josh Barnett isn’t one to brag about victories inside the cage, but Frank Mir gladly will if he takes out Barnett.

The two will square off in the co-main event August 31 at UFC 164.

While Barnett told reporters during a recent conference call that it is up to “the winner, I guess,” to brag if he wants, Mir sees his bout with a fellow former UFC heavyweight champion as a chance at proving himself.

“I look at it as bragging rights to get a victory over Josh,” Mir said. “Where he was when I came in, his career; Josh was the champion when I first got into the UFC.”

Mir, who has wore the belt as unified and interim champion in the past, knows nothing will come easy vs. Barnett, also an accomplished submission grappler.

“I have fought people before that never tapped out,” he said. “I have to respect that, but I can’t second guess (myself). I have to fight the fight and have to link four, five, submission attempts together.”
