Heavyweight Heath Herring, who had been scheduled to fight Cain Velasquez in the co-main event at UFC 99, will not fight on the card as scheduled, FanHouse learned Tuesday.

FanHouse's Ariel Helwani first got the news that Herring is out. I separately confirmed with a source close to Herring that he has been battling an illness for weeks and unable to train.

It is not known at this point what will happen with Valasquez, a former Arizona State wrestler who is one of the brightest young heavyweight prospects in the UFC.

Could this mean that Cro Cop will step into face Valasquez? The fight is off the UFC 99 page, I guess we will see what happens.
