Following their loss to the Penguins, they learned that their plane had been damaged on the tarmac at the airport, forcing them to extend their stay in Pittsburgh.
A tanker truck collided with the plane, hitting the wing and making it impossible for them to return immediately to Montreal.
RDS journalist Patrick Friolet, as well as TVA Sports' Renaud Lavoie confirmed that the incident occurred during the match, while the players were not on the plane.
This isn't the first time the Habs have been the victim of an incident like this: last year, a bus damaged the team's aircraft.
This situation comes on top of the Canadiens' three consecutive losses, a blow as they seek to get back on the winning track.
They will, however, have the opportunity to bounce back on Tuesday at the Bell Centre, where they will face the Calgary Flames, who have had a good start to the season but have been struggling in recent games.
Fans are hoping that a return home will wake up the troops, although the team's two worst losses this season came at the Bell Centre, against the New York Rangers and, last Tuesday, against the Seattle Kraken.
