Detroit Red Wings defenseman Mike Green will miss the start of the season as he battles a virus that attacked his liver, according to coach Jeff Blashill.Green had complained of low energy and felt fatigued, prompting the Red Wings’ doctors to take some bloodwork. The 32-year-old has been informed to stay off the ice as his health situation is investigated.”He’s got a virus that attacked his liver, so he’s seen an infectious disease person today and we should know more here in the next little bit,” Blashill told reporters. “I don’t know how long he’s going to be out. I don’t know the totality of it. He’s got a virus.”The challenge comes after Green underwent neck surgery in April. He was cleared to return just prior to the opening of training camp.”The day before camp he saw the doctor in New York on his neck, he was totally cleared, cleared for contract,” Red Wings general manager Ken Holland told reporters. “The plan was to ramp him up and play him in two of the last three preseason games. As we got into camp and were on the ice two, three, four days he didn’t feel like he had his energy, he felt a little bit fatigued.
