More than likely we'll see this one on the Fury/Haye undercard. either that or we'll see Chisora/Thompson.
Chisora fights for Wa55en. he'd never let his fighters fight on a Hearn bill because he hates the man. but to answer the question: Chisora stops him late in a surprisingly good fight.
Charr is weak copy of Chisora. Derek outboxes him during 10 rounds and stops in the next two rounds. Charr has no stamina as well. Brittish stoppage like those in Gerber and Pala fights is likely to happen.
The leftovers of Vitaly . . Chisora has changed to a jurneyman, he ist not a contender anymore and never was Charr..
They're both very much alike, but you may be right that Chisora is the better version. I think it might actually be a lot more competitive than you think though. The two are just meant to fight each other, kind of like Ustinov and Wach.
charr at this point ...he hits harder has great chin and chisora has no punch at all and he is so shot that charr would knock him out ....
