The Habs held the Senators to 1 shot attempt for the first 6:14 of the 1st period, putting some pressure on Craig Anderson with 3 shots on 7 attempts. The Canadiens looked to be building something while the Senators looked like they were trying to keep up.
Tomas Plekanec would beat Craig Anderson, but Brendan Gallagher was deemed to have interfered with Anderson so the goal was called off. Michel Therrien used his coach's challenge, but it was obvious Gallagher impeded Craig Anderson's path to make the save in the blue paint, and the call remained the same.
