Rick Nash, a 34-year-old left winger and one of the most prolific scorers in recent NHL history, has retired due to concussion-related symptoms, his agent announced Friday.

"Due to unresolved issues/symptoms from the concussion sustained last March, Rick Nash will be forced to retire from the game of hockey. Under the advice of his medical team, the risk of further brain injury is far too great if Rick returns to play," his agent Joe Resnick said in a statement. "Rick would like to thank everyone who has supported him during this difficult time period."

Barry Trotz moved into fourth place on the NHL's all-time coaching wins list when his New York Islanders beat the Buffalo Sabres 3-1 on Monday night.

Trotz picked up his 783rd career victory and passed Islanders franchise legend Al Arbour on the list.
