Washington Capitals Defenseman Karl Alzner will miss his second straight game with an upper-body injury when the Capitals face the Toronto Maple Leafs in Game 4 of the Eastern Conference First Round at Air Canada Centre on Wednesday (7 p.m. ET; NBCSN, CBC, TVA Sports 2, CSN-DC).

Alzner, 28, did not participate in the Capitals' 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 had played in 599 consecutive games, including the regular season and the Stanley Cup Playoffs, before missing the Capitals' 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 at Bell Centre on April 26, 2010.

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