Toronto’s injury bug has now claimed Kasperi Kapanen.

The Leafs right winger, who was flourishing with Auston Matthews much of this season, is now being listed by the team as having a concussion. He was not feeling well after Monday’s morning skate and was pulled from the lineup against Tampa Bay as a precaution with what observers thought was the flu bug going around the room. But he was likely rattled at some point during Saturday’s game in Edmonton.

William Nylander will remain on Matthews’s side with Andreas Johnsson, while no other lineup changes are planned for Wednesday’s home game against Chicago.
