Romanov cut it to 3-2 at 1:04 of the third period. He scored on a one-timer over Grubauer's right shoulder from the top of the left face-off circle.
Canadiens defenseman Joel Edmundson made his season debut in Montreal's 58th game after recovering from a back injury. He had two shots and six hits in 16:38 of ice time. Edmundson will not play at the Philadelphia Flyers on Sunday in a decision made after consultation with team doctors.
"There's a few shifts where I was trying to catch my breath and started to cramp up in the third," Edmundson said. "But it's just nice to get back out there with the guys, and I think over the next couple of games I'll get back into game shape."
NOTES: The game was played in front of the first capacity crowd in Montreal since Dec. 9 after COVID-19 restrictions in the province of Quebec were lifted. … Johansson's first assist, on Donato's goal, was his 400th NHL point.
