At least, that's what Renaud Lavoie mentioned. Without expressing his personal opinion, he heard that the towering defenseman could be back this week.
Considering that Struble has been solid with the Canadiens, Norlinder needs playing time, and the possibility of Armia taking the place of Pezzetta or Ylonen, who play no more than 6-7 minutes per game, we have a good clue that Norlinder might be sent down.
It's not confirmed, and the Canadiens are unlikely to make an announcement before tomorrow or Wednesday if Xhekaj returns to play. However, all signs point in that direction.
