San Jose Sharks captain Rob Blake is retiring from the NHL after a 20-year career as one of the league's top defensemen.

Blake will make the retirement official at a news conference on Friday, a person with knowledge of his plans told the Associated Press yesterday. The person spoke on condition of anonymity because the announcement has not been made. Comcast SportsNet Bay Area first reported Blake's retirement plans.

Blake, 40, won the Norris Trophy as the NHL's top defenseman for Los Angeles in 1998.
