Max Pacioretty took a pick to the side of the head against the Canadiens and while he did seem to be okay in the moment, there is no doubt that the after-effects have been quite damaging.
To make things worse, the Leafs are putting the veteran forward on the injured reserve which means he won't be available this weekend as the team takes on the Ottawa Senators.
The Maple Leafs are currently in the midst of a three-game winning streak and they are also first in the Atlantic Division with a three-point lead on the Florida Panthers.
With games against the Blue Jackets and the Senators coming up, there is no doubt that this Leafs team needs to step it up and keep their feet on the gas.
