It was Backstrom’s second straight game out of the lineup with an injury to his right hand sustained in Game 5 of Washington’s series against Pittsburgh.
Backstrom has three goals and 10 assists in 11 games this postseason, including one overtime game winner. The 30-year-old center had 71 points in 81 games during the regular season.
He skated Thursday at the Capitals’ practice facility in Virginia, working on some stickhandling and passing, but he did not practice.
Capitals coach Barry Trotz said that when Backstrom says he’s ready, he’ll be in the lineup.
