According to ufc.com:
A broken foot has forced light heavyweight James Irvin to withdraw from his UFC 85 showdown with Rashad Evans (16-0-1) at London’s O2 Arena. Stepping up to replace ‘The Sandman’ against Evans is Brazil’s Luiz Cane (8-1), who was originally scheduled to face Jason Lambert on the June 7th card.
June 7th’s UFC 85: Bedlam show has finally been set with 11 fights. Included is a move of the intriguing middleweight clash between Nate Marquardt and Thales Leites to the pay-per-view portion of the card, and a scrapping of the Rashad Evans vs James Irvin bout due to a broken foot suffered by Irvin.
