Just read some russian news according to which the contract had been signed by both fighters, and the fight will take place in O2 Wolrd Arena in Berlin on Ocober 11th.
I believe this fight will happen come fight day. The odds that it falls through from injury to either guys is probably 50/50.
I think both fans and non-fans hope Vitaly does not get injured again, so we can finally watch an entertaining HW fight.
Don't count your chickens before they hatch. When's the last time Vitali made it out of training camp?
