Auston Matthews will not be in the lineup for the Toronto Maple Leafs when they host the Winnipeg Jets at Scotiabank Arena on Thursday (7 p.m. ET; TSN4, TSN3, NHL.TV) because of an undisclosed injury.

Matthews is day to day. He leads the NHL with 32 goals and is tied for fourth with 53 points.

"We're not expecting it to be something that is going to hold him out for long," Toronto coach Sheldon Keefe said.

Matthews was the first player on the ice for the Maple Leafs morning skate but left prior to the main session beginning.
