Toronto Maple Leafs captain Auston Matthews formally returned to practice Friday, after working through a lower-body injury incurred during training camp.

Toronto Maple Leafs coach Craig Berube said he does not think Auston Matthews’ upper-body injury is too serious and expects the captain to be fine. Matthews returned to practice Thursday after getting a couple of days off the ice for what Berube called maintenance.

Fans in Toronto got nervous on Tuesday when Maple Leafs captain Auston Matthews left the ice midway through Tuesday’s practice and did not return. After the skate, head coach Craig Berube sort of dismissed any concern, saying: “Just an upper-body thing. It’s not serious. He should be fine.”
