"According to the Boston Globe, defenseman Zdeno Chara feels better than expected. And that's excellent news for the Boston Bruins. Considered "doubtful" for Tuesday's contest with the Los Angeles Kings, Chara is considered day-to-day."
From what I have been reading he will be out for tonight's game and tomorrow's, but he could be back for Saturday's game against the Flyers. The Bruins are going to miss Chara, as he has been awesome this year, but at least it sounds like it's a short term injury and not something more serious.
