Following news that UFC heavyweight champion Frank Mir would not be ready to return to the Octagon in October, the UFC will likely hold its interim heavyweight champion, Andrei Arlovski, off Fall's UFC 55 card, Sherdog.com learned Tuesday night.

Budding superstar Forrest Griffin, who will be all over television thanks to Spike TV's push of season two of the "Ultimate Fighter," including an August appearance on CBS's Late Show with David Letterman, could get the opportunity to headline the October card, UFC president Dana White told Sherdog.com.
