The family of former enforcer Derek Boogaard filed a wrongful-death lawsuit against the NHL, blaming the league for brain damage he suffered and for his addiction to prescription painkillers. Boogaard died of an accidental overdose of pain medication and alcohol two years ago; his body was found on May 13, 2011. The 28-year-old was posthumously diagnosed with chronic traumatic encephalopathy, a degenerative brain ailment that can be caused by repeated blows to the head, according to the 55-page lawsuit filed in Cook County (Ill.) Circuit Court late Friday. An attorney who filed the lawsuit, William Gibbs, said Monday the NHL profited from Boogaard’s abilities as team doctors dispensed ‘‘pain pills like candy’’ after he suffered repeated injuries. Boogaard scored only three goals in his six-season career in 277 regular-season games, but took part in at least 66 on-ice fights. In the 2008-09 season with Minnesota, he received 1,021 prescriptions from team physicians, dentists, trainers, and staff, the lawsuit says . . . Veteran NHL coach Mike Keenan signed a two-year contract with Russian club Metallurg Magnitogorsk. Keenan, who amassed more than 600 wins over 25 years and won the Stanley Cup with the Rangers in 1994, last coached for Calgary from 2007-09 . . . Marc Bergevin of the Canadiens, Bob Murray of the Ducks, and Ray Shero of the Penguins were all named as first-time finalists to be the NHL’s general manager of the year . . . Steven Stamkos scored two goals and Canada rallied for a 4-3 overtime win over Slovenia at the world championships in Helsinki. Also, Russia defeated Austria, 8-4, behind a goal and two assists from Ilya Kovalchuk. The results relegate Austria and Slovenia to the second tier of the worlds. They will be replaced by Kazakhstan and Ukraine.
