Anything can happen, I don't think so though, I know he will give it a good go so it might make for a couple of interesting early rounds.
I'll wager he can make it out of the first round, Wlad usually starts slow. It's such a huge skill gap for Chisora though, the shock of the transition might be too much for him.
Yea he could probably make it through round one, unless he talks **** to Wlad like Austin did and gets him mad.
