Gonchar was removed in the first period of Saturday's game against the Maple Leafs due to an upper-body injury and will not return, Arpon Basu of LNH.com reports.Gonchar was the recipient of a blindside hit into the boards by the Leafs' David Clarkson, resulting in an ejection for the Toronto forward. The Habs are listing Gonchar as day-to-day for now, but it wouldn't be a surprise if he was forced to miss time, as his head appeared to collide violently with the glass. The team should offer an update on his condition ahead of Monday's tilt with the Red Wings.
