Canadian ice sledge hockey Paralympic gold medallist and two-time world champion Graeme Murray has retired as he targets mentoring future stars.
Murray, one of his country's most accomplished ice sledge hockey stars, won gold at Turin 2006 and bronze earlier this year in Sochi.
In 2008 and 2013, he won gold at the International Paralympic Committee Sledge Hockey World Championship and bronze in 2009 and 2012.
He has also won four World Sledge Hockey Challenge titles, most recently last year.
"It is not an easy choice to hang up my sled," said the 29-year-old.
"I am not finished with sledge hockey as I want to be involved in a mentorship role and contribute to the promotion of this sport.
"I feel it is time for me to move on to new and exciting things.
"I am proud of my career and excited about the future."
The Gravenhurst, Ontario, native, ends his career with 33 goals and 31 assists to his name in 163 games since the national team came under the Hockey Canada umbrella in 2004.
He ranks tied for third in all-time games played, sixth in scoring and second in scoring among defencemen.
Scott Salmond, vice-president of hockey operations and national teams with Hockey Canada, said: "We cannot thank Graeme enough for his dedication not only to Canada's national sledge team over the past 13 years, but to the growth and development of the sport across the country.
"We wish him nothing but the best in whatever his future holds, and know he will continue to be an ambassador for the game."
