I was about to say "It'd be interesting if Haye decided to take to MMA as he's still relatively young"
Until I saw this photo in this article
Dereck Chisora brawls with David Haye: Thugs face life ban | The Sun |Sport|Boxing
Pretty damming evidence Haye defintely bottled Chisora, as you can see what's left of the bottle still in Davids clenched fist. Although it doesn't look like the bottle actually impacted on Chisora's face, it was a stupid thing to hold onto that bottle, and a stupid thing to do through and through.
