We wish the best for TUF 15 winner Michael Chiesa (8-0), as the UFC announced late last night that he will be unable to compete due to illness. No further details have been released at this time. With only five days till UFC on Fox 5: Henderson vs. Diaz, it will be a tough call for any fighter to take this late, which will likely leave Chiesa’s opponent Marcus LeVesseur off the card.

This is the second bout to fall just days short of the event as Lavar Johnson had pulled out with a reported groin injury. As the card currently stands currently, there is 11 bouts on the card, with a second Facebook prelim bout now likely to shift up to the FX portion of the show.
