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."
It is really special. I had a lot of friends and family here tonight, and for my first [NHL] game in here it was great. I played here as an elementary-school player in the city championships and this was my first time back. It was a lot of fun.
