The man who knocked over Anthony Joshua says Joseph Parker's team is "clutching at straws" in the way they have attacked Joshua.
Joshua's chin has been turned into a major talking point by Camp Parker, as the boxers prepare for the heavyweight unification bout in Cardiff at the end of March.
British heavyweight David Price has detailed flooring Joshua during a sparring session, in the wake of the Parker camp's claims about Joshua's ability to take a big punch.
Price has told Sky Sports the incident occurred during their only sparring session, in 2011.
"They are clutching at straws. It's funny that the world champion is having to justify his chin," the 34-year-old Liverpudlian said.
