Alzner did not participate in an optional practice Tuesday and has not been on the ice since a 4-3 double-overtime loss to the Maple Leafs in Game 2 at Verizon Center on Saturday.

"He's out right now and he won't play [Wednesday]," Capitals coach Barry Trotz said.

Alzner played in 599 consecutive games, including the regular season and the Stanley Cup Playoffs, before missing a 4-3 overtime loss in Game 3 on Monday. Before that, the last time Washington played a game without Alzner was Game 6 of the 2010 Eastern Conference Quarterfinals against the Montreal Canadiens on April 26, 2010.

Alzner's streak of 540 consecutive regular-season games is the fifth-longest active streak in the NHL.

The Capitals trail the Maple Leafs 2-1 in the best-of-7 series. Nate Schmidt is expected to take Alzner's place in the lineup again Wednesday. Schmidt played 16:29 and assisted on the Capitals' first goal, scored by Nicklas Backstrom, in Game 3.
