Canada's world number one Jonathon Power has announced his retirement.
Jonathon Power started playing squash at the age of seven
The 31-year-old, who's just returned to the top of the world rankings, will not defend the Commonwealth title he won beating England's Peter Nicol in 2002.
"Retiring has been a very difficult decision for me," said Power, who won 37 tour titles in his career.
"But I recognise that, with my health being strong, I can use this next phase of my life as an active ambassador and catalyst for the growth of squash."
Power, who turned pro at the age of 16, was one of the most colourful players on the circuit and was described as squash's John McEnroe.
He won the World Open crown in 1998 as well as winning gold at the 2002 Commonwealth Games.
The Toronto-based player won five PSA Tour titles last year and reclaimed the world number one spot for the first time in four years.
His impressive form continued in 2006 as he reached the final of the opening two events of the year.
"Jonathon's decision to retire signifies the end of an era in the professional game," said PSA chief executive Gawain Briars.
"Whilst his form has been understandably patchy in this last period due to ongoing injury issues, his mercurial talent was still sufficient to elevate him again to the pinnacle number one position in the world.
"Jonathon has been the iconic figure of his time.
"His much publicised and acknowledged brand of showmanship and extraordinary racket skills have carved him out a special place in the hearts of fans, not just in squash but throughout sport in general."
Power takes up his position with a squash marketing and development company on 1 April.
