Ailing back ends Red Wings star Zetterberg’s career

Henrik Zetterberg’s NHL career is over due to a degenerative back issue, Detroit Red Wings general manager Ken Holland said Friday as training camp opened.Zetterberg was holding out hope he could return for a 16th season, but had already been ruled out of being ready for the start of the season .According to Holland, Zetterberg will go on long-term injured reserve. He has three years remaining on a 12-year deal.Zetterberg, who turns 38 in October, told reporters at the end of the regular season in April that he would have to evaluate his health before deciding whether to retire.”I don’t want to think I have played my last game,” the left winger told the Free Press then.Zetterberg has fought through back issues since undergoing surgery in 2014, but despite playing all 82 games in each of the past three seasons, the back has affected him.
