Spacek returns as Gill, Markov sit out

MONTREAL -- Canadiens defensemen Andrei Markov and Hal Gill did not play in Monday's do-or-die sixth game against the Penguins.

However, fellow defenseman Jaroslav Spacek returned to the lineup after sitting out nine games because of an undisclosed virus. He last played in Game 3 of Montreal's first-round win over Washington.

Gill missed most of the third period of Game 5 after sustaining a cut on the back of his leg when he got tangled up with Chris Kunitz and then had to spend almost all of Sunday trying to get from Pittsburgh to Montreal, arriving late Sunday night.

"They wanted to make sure everything was all right so they took their time with it," said Gill, who returned to Montreal with Canadiens team physician Dr. David Mulder on Sunday.

Gill has been a significant part of the Canadiens' ability to shut down Alex Ovechkin and the Capitals in the first round and then to keep Pittsburgh captain Sidney Crosby from scoring through the first five games of this series.

The Canadiens trail Pittsburgh 3-2, though, and must win Monday to force a second straight seventh and deciding game.

"It's encouraging. It shows a lot of character on his part to get back last evening and get some treatment this morning," Martin said.

As for Markov, who suffered a knee injury in Game 1 of this series, Martin said he will not play even though he has been on the ice the last couple of days. On Monday, he skated in full equipment before his teammates took the ice for the morning skate.

"His condition is indefinite," Martin said of Markov. "He's ruled out for tonight."
