TORONTO - Defenceman Mike Weaver has announced his retirement after 11 NHL seasons, most recently with the Montreal Canadiens.

Weaver played in 633 regular-season and 28 playoff games for the Atlanta Thrashers, Los Angeles Kings, Vancouver Canucks, St. Louis Blues, Florida Panthers and Canadiens.

Undrafted out of Michigan State University, the five-foot-ten Weaver helped Montreal reach the Eastern Conference final in 2014.

Weaver said in a statement released by the NHL Players' Association that he "never could have imagined" a career like this.

The 37-year-old native of Brampton, Ont., will continue working with his defensive hockey school, Defense First, in retirement.
