An official with the Royal Canadian Mounted Police called Rypien's death sudden, but not suspicious. Rypien, a cousin of Super Bowl MVP quarterback Mark Rypien, was 27.
"We would like to express our sincere sympathies to the Rypien family as well as Rick's friends," the Jets said in a release. "We also appreciate all of the support that has come pouring in from Rick's fans. Rick was a talented player with an extremely bright future. His hunger for the game made him a valued team member both on and off the ice. This loss has impacted us as more than just a hockey team."
The 5-foot-11, 190-pound Rypien signed a $700,000, one-year deal with Winnipeg last month after spending parts of six seasons with Vancouver. He had nine goals, seven assists and 226 penalty minutes in 119 career NHL games, often dropping the gloves against much larger opponents.
"Rick has been a beloved member of the Canucks family for the past six years," the team said in a statement. "Rick was a great teammate and friend to our players, coaches and staff. We send our deepest condolences to the Rypien family at this most difficult time."
The Canucks announced on Nov. 25 that they had granted Rypien an indefinite leave of absence. It was the second time in three years the forward had left the team to deal with an undisclosed personal matter. Rypien also received a six-game suspension from the NHL last season after grabbing a fan on his way to the dressing room in Minnesota.
Rypien also took an extended personal leave after a rash of injuries two years ago, missing 70 games during the 2008-09 season.
"All players and NHLPA staff are saddened to learn of Rick's passing," union executive director Don Fehr said in a statement. "He was a respected member of our association and will be greatly missed throughout the hockey community. Our sincere condolences go out to Rick's family, friends and many fans."
