Karlsson (undisclosed) is considered highly doubtful for Monday's contest against the Red Wings, Bruce Garrioch of the Ottawa Sun reports.

EDGE Analysis

While he hasn't been officially ruled out, it appears the star blueliner will miss at least Monday's contest in addition to the previous two. The club should provide an official word on his status, but consider him out unless something notes otherwise. Assuming that's the case, it's a quick turnaround for a road game rematch with the Red Wings on Tuesday, so it's questionable if he will make it back in time for that tilt.
