It's really unfortunate, but once again, a player fell in the line of duty, yesterday with the Canadiens. Rafaël Harvey-Pinard got injured during the game, and although he attempted a return, it was impossible for him to finish the match.
The only problem is that Monahan is crucial at center, especially since Kirby Dach is injured. However, there is a change. Christian Dvorak will finally be able to come off LTIR and make a return to the game in the coming days, giving this option to Martin St-Louis.
The other option, as mentioned by Marc-Olivier Beaudoin, would be to put Tanner Pearson on the first line, and Sean Monahan would lead a line with Alex Newhook and Juraj Slafkovsky.
In any case, Dvorak's return will certainly provide a boost to Monahan, who has been the team's best forward since the start of the season.
