Former world heavyweight champion David Haye has retired again from the ring.
Haye, 37, is also a former cruiserweight world champion and ends his career with a record of four defeats in 32 fights.
He lost his last fight in May, a heavyweight rematch against fellow Briton Tony Bellew, after losing the first contest in March 2017.
Haye also announced his retirement in October 2011, three months after losing his WBA belt to Ukrainian Wladimir Klitscho in Germany, but he returned to the ring the following year.
