Gallagher is now on the second line, alongside Torrey Mitchell and Paul Byron. This means that Brian Flynn has been relegated to the third line with Artturi Lehkonen and Tomas Plekanec. Those were actually the same lines as yesterday, but with the order switched. The first and fourth lines remain unchanged.
As for the defence, they had to adjust to the loss of Andrei Markov.
Nathan Beaulieu has earned a promotion, now slotted beside Jeff Petry. Mark Barberio and Zach Redmond will complete the second pairing, whereas Alexei Emelin and Shea Weber will once again absorb first pairing responsibilities.
This will be the first game Andrei Markov misses since April 3rd 2015.
On to special teams, a sore spot of late. The Canadiens also practiced their power play setup.

*Gallagher rotated w/ 24 & 34 on each unit.
I'm not convinced we'll see that second unit in action at any point tonight, but it's an interesting line to say the least, with two of the three forwards being rookies.
