Cain Velasquez has been forced out of a fight due to physical issues.
The news was first reported by ESPN.com. The NSAC was unavailable for comment.
According to the ESPN story, the Nevada State Athletic Commission (NSAC) failed to approve Velasquez (14-2 MMA, 12-2 UFC) to fight, determining after physical examinations and interviews he was unfit to compete. Velasquez, ranked No. 2 in the USA TODAY Sports/MMAjunkie MMA heavyweight rankings was set to fight Fabricio Werdum (21-6-1 MMA, 9-3 UFC), the man who took the title off of him at UFC 188.
