The Detroit Red Wings expect defenseman Mike Green to miss the first four weeks of the regular season as he recovers from a virus that attacked his liver.”We think it’ll be two more weeks before he’s in full practices, which would leave with two more weeks after that before he’s ready to go,” coach Jeff Blashill said Tuesday, via the Red Wings’ website. “We’re looking at a timeline of a month before we’d have him fully available to us. That timeline is fluid, but that’s what we’re looking at.”Green complained of low energy and felt fatigued last month, prompting the Red Wings’ doctors to take some bloodwork. The 32-year-old was informed to stay off the ice as his health situation was investigated, though he since has returned to skating on his own.Green scored 33 points (eight goals, 25 assists) in 66 games last season. His campaign ended prematurely due to the neck injury.
