Auston Matthews, the captain of the Toronto Maple Leafs, missed practice and is considered 'doubtful' for the upcoming game against the Ottawa Senators due to an upper body injury. General Manager Brad Treliving confirmed that Matthews is day-to-day but hopes to resolve the situation soon.

Max Pacioretty is on injured reserve and is classified as 'week-to-week' following a hamstring injury sustained during a game against the Montreal Canadiens. Other players like William Nylander and Max Domi also missed practice for maintenance reasons, while Calle Järnkrok is dealing with a sports hernia.

On a positive note, Connor Dewar has been cleared to play and is expected to make his season debut, and Jani Hakanpää is awaiting medical clearance after being called up from the Marlies.
