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. http://sports.espn.go.com/nhl/playoffs/2010/news/story?id=5177495
