Contrary to reports from other sources, Heavy.com learned from sources close to the UFC on Tuesday afternoon that a contender's bout between Vitor Belfort and Nate Marquardt is "not happening".

Belfort was scheduled to face Anderson Silva on the card, but Silva's recovery from elbow surgery has taken longer than expected and he won't be available to fight on the card. There's no specific timetable for Silva's return at this time.
