Montreal Canadiens center Alex Galchenyuk and defenseman Jeff Petry are expected to play Thursday. Galchenyuk missed the previous three games because of a right knee injury. Petry didn't play in a 5-2 win against the Buffalo Sabres on Tuesday because of the flu. That game against the Sabres saw the return of defensemen Andrei Markov, who had missed 19 games because of a groin injury, and center David Desharnais, out 24 games with a knee injury. That leaves forward Brendan Gallagher, out until March because of a hand injury, as the only key player missing from the lineup. Despite those injuries the Canadiens lead the Atlantic Division by nine points. "The last two months were pretty rough health-wise, and we were still capable of maintaining our quality of play compared to, I would say, last year," Canadiens coach Michel Therrien said Wednesday. "So that's good news for us. Obviously it's a big boost to get some of our players back." Galchenyuk will center a line with Desharnais at left wing and Andrew Shaw at right wing. "[Desharnais] is a playmaker," Galchenyuk said Wednesday. "I can make plays but I'm more of a shooter. And [Shaw], you always need guys like that on your line. Works hard, competes, does the little things right."
