Oliver Harrison, former trainer to Amir Khan, Jamie Moore and Martin Murray, has died at the age of 58.

The Manchester-based coach had overseen the early stages of Khan's professional career and enjoyed success as he trained Moore, Murray and Rocky Fielding.

Harrison guided Moore to British, Commonwealth and European titles, while he worked with Murray as he came within touching distance of a world middleweight title in four attempts, and also helped Fielding to rise the super-middleweight ranks before illness curtailed his time in the corner.

Very sad to hear of the death of Oliver Harrison. A top trainer & a real gentleman. Boxing has lost a great servant. Thoughts & prayers are with his family & @JamieMoore777 @MartinMurrayBox & all the lads that trained with him who were very close to him.

Adam Smith, head of Sky Sports Boxing, said: "We are all deeply saddened by the death of Oliver Harrison. He was a caring and wonderful man, as well as a highly-respected trainer.

"I spent a lot of time with Oliver over the years, a really dignified person who stayed away from the spotlight as his impressive results spoke for themselves.

"Oliver was a calming influence in the corner as Moore, Murray and Fielding enjoyed some of the finest nights of their careers, and we'll miss that winning smile."
