Florian was scheduled to face rising prospect Dunham in the headlining bout of the Fight for the Troops 2 show on January 22 at Fort Hood, TX. Melvin Guillard has been pulled from his bout with Yves Edwards and will face Dunham in the new main event.
There's no word yet on a new opponent for Yves Edwards, or on the specific nature of Florian's injury, but stay tuned to Bloody Elbow for updates.
UPDATE: Kenny Florian discusses the injury on his website:
It is with deep regret that I will not be able to compete in my scheduled fight against Evan Dunham on January 22nd, due to a knee injury I sustained during training this morning. Although I have not had an MRI as of yet; the doctors are cautiously optimistic that it will not require surgery.
I want to express my sincere apologies to the fans, the UFC and Evan for not being able to compete at UFC Fight Night 23: Fight for the Troops 2. Since early September, I have been training for this fight. Evan is a great fighter and has undoubtedly been working very hard towards this fight as well. Plus, it is a big disappointment that I will not be able to fight in the octagon for the brave soldiers that fight for us.
I am determined to return to the octagon in the first half on 2011. Accordingly, I will keep you all updated.
