Tyson Fury’s troubled 11th month reign as world heavyweight champion came to an end on Thursday when the British boxer announced he would be vacating his WBO and WBA titles “to fully focus on his medical treatment and recovery”. The 28-year-old has not fought since beating Ukrainian Wladimir Klitschko to win the titles in November 2015 and has since admitted taking cocaine to battle depression. Fury has twice called off a fight against Klitschko, in July because of an ankle injury and last month for an unspecified medical condition, and also briefly retired from the sport.
