Maple Leafs coach Randy Carlyle revealed the nature of the injury this morning.
"[Gunnarsson] had an MRI done and he has an ailment in his hip area that is causing a little bit of discomfort," Carlyle said. "There is no muscular tear. He irritated it probably when he first came over after lockout … he should be back with us shortly."
There's no discouragement in that room. There's no issues there at all to be honest with you. It's more about, 'Hey, it's opportunities for players.' And if we become that bad of a team because of one player, it's not a real good sign for our hockey club. So this is part of sports. It's part of hockey.
