Matthew Knies joins a long list of injured Leafs that has had a trickle-down effect on the rest of the lineup.

Toronto Maple Leafs head coach Craig Berube revealed that forward Matthew Knies is day-to-day with an upper-body injury. Berube also stated that he doesn’t know when he will be available to return to the lineup.

Matthew Knies was injured in the second period of Toronto's game Wednesday against the Columbus Blue Jackets. Knies struggled to get up from the ice after colliding with Blue Jackets forward Kirill Marchenko and did not return to the game. Knies was ruled out with what the Maple Leafs called an upper-body injury.
