#4 Leon McKenzie
Leon McKenzie scored 115 goals in 393 games at club level, winning promotion to the Premier League with Norwich City in 2005.
However, his career was stalled by recurring injuries and he dropped down the divisions with clubs such as Charlton Athletic, Northampton Town and Coventry City.
With his personal life in disarray and constant money worries, McKenzie saw no way out and tried to commit suicide at the age of just 31. His father, Clinton, saved his life and kept Leon by his side in the boxing gym he ran; eventually encouraging his son to don the gloves himself. Clinton had fought Sugar Ray Leonard at the 1976 Olympics and he took up the job of training Leon himself.
McKenzie fought for the first time in 2013, winning 8 and drawing 1 of his first 9 fights, picking up an International Masters belt, before finally losing his first game last month.
However, the record seems insignificant in this instance, with boxing giving him a new lease on life; quite literally.
