Karl Alzner has been ruled out for Game 1 of the Capitals’ second round matchup against the Penguins on Thursday night.

Although the veteran defenseman has been ramping up his workload in recent days, Washington will ice the same lineup it used in the series clinching win over Toronto, Coach Barry Trotz confirmed after the pregame skate in Arlington.

Alzner has been sidelined since Game 2 of the Maple Leafs series with an upper body.

Trotz indicated that Alzner has not received medical clearance to return to game action.

“We’re not going to put him at risk,” Trotz said. “He’s day-to-day.”

Nate Schmidt, who owns a team-best plus-5 rating in the playoffs, will again replace Alzner in the Capitals’ lineup as hockey's most anticipated matchup of the postseason opens at Verizon Center.
