The British pair clashed at the post-fight news conference following Chisora's defeat to Vitali Klitschko.
"It was unacceptable. It is stupid. It does not do anybody's sport any favours - boxing or whatever," Warren told BBC Radio Five Live.
"It is just ridiculous. It takes away from what was a gallant showing from Dereck in the ring."
Chisora has been arrested for his role in the altercation, while German Police are still trying to locate the whereabouts of Haye.
