Auston Matthews was hurt on this play in front of the net:

The hit happened in the second period, and Matthews did not return to the game. In keeping with the new way of things in the NHL — more on that Monday as the league announces their new gambling initiatives — the Leafs came right out and said it was a shoulder injury during the game.

After the game, Mike Babcock spoke to the press:

The Leafs next game is Monday against the Flames.

The post-game, where Babcock confirms it’s not the same shoulder as last year.
