Colorado Avalanche center Nathan MacKinnon left the 5-3 loss to the Philadelphia Flyers on Monday with an upper-body injury, the team announced.

MacKinnon took a wrist shot from the slot in the first period, and as the puck sailed wide of the net, he winced but remained on the ice and finished his shift. When he went to the bench, the game broadcast showed a shot of him favoring his left side.
