Chisora will next fight on Frank Warren's Copper Box Arena show on September 21, which also features Billy Joe Saunders' British middleweight title showdown with John Ryder.
"This is the new Dereck Chisora back on the road to winning the world heavyweight title," Chisora said.
"Kubrat for the European title would be nice and he's going to get knocked out – or bring me another unbeaten Yank to spank like Deontay Wilder."
