Kronwall's injury has been diagnosed as a sprained knee and will keep him out for 1-to-3 weeks, Helene St. James of the Detroit Free Press reports.

Analysis:

This is the second knee injury that Kronwall's suffered this season, though this time it was to the other knee. Kronwall's production has dipped below normal levels this season (three goals and 20 points in 53 games), but he will be missed dearly by the Red Wings as they fight to stay in the playoff picture. Expect Alexei Marchenko to step into the lineup in Kronwall's place for the time being.
