Montreal Canadiens forward Andrew Shaw will not play against the New York Rangers his the team's season on the line in Game 6.

Shaw has been ruled out with an upper-body injury, but is suspected to be dealing with a concussion. He took a hard hit overtime of Game 5 from Dan Girardi and was also involved in a fight with Brendan Smith in the first period of the 3-2 overtime loss.

Shaw has yet to register a point and is a minus-2 with seven penalty minutes through five games. 

Brian Flynn took Shaw's place skating on the third line at practice with Alex Galchenyuk and Artturi Lehkonen.

Shaw will be joined in the press box by defenceman Nathan Beaulieu, who will serve as a healthy scratch.

Beaulieu has also played in all five of Montreal's playoff games. He's registered just one assist. Brandon Davidson will take his place, having been inserted in the lineup twice this postseason, averaging 11:29 minutes of ice time. 

Davidson was acquired from the Edmonton Oilers on February 28th for David Desharnais. 

Also missing from the lineup in Game 6 will be centre Torrey Mitchell. Michael McCarron, 22, will take his place.

Mitchell scored one goal in three playoff games against the Rangers.

McCarron will start his first career playoff game on Saturday. The 2013 first round pick had a goal and four assists in 31 games with the Habs in the regular season. 

Montreal is down 3-2 in their best-of-seven series, a win Saturday will push the series to a Game 7 on home ice.
