July 2011 - Haye blamed his defeat to Wladimir Klitschko in their world heavyweight title unification fight on a broken toe on his right foot that he suffered in training. Haye said the injury had hampered his movement, but the excuse drew widespread ridicule.
May 2013 - Then aged 32, and preparing to fight for the first time since the previous July, this time against Manuel Charr, Haye withdrew with a hand injury. Their match-up was never rescheduled; he instead agreed to fight Tyson Fury.
