The injury-riddled Detroit Red Wings learned on Monday that centre Darren Helm will be out four to six weeks with a sprained MCL.
Detroit is already without captain and defenceman Nicklas Lidstrom (deep bone bruise in his right ankle), defenceman Jonathan Ericsson (broken left wrist), defenceman Jakub Kindl (strained oblique), right wing Johan Franzen (back spasms) and goalie Joey MacDonald (back).
Helm was hurt in Saturday night's 3-2 overtime loss in San Jose.
Monday's game against Washington is the 10th consecutive game that Lidstrom has missed, the longest stretch of time he's been unable to play in his 20-year career.
Lidstrom skated for more than a few minutes on Monday morning for the first time in three weeks.
