Toronto Maple Leafs leading scorer Mitch Marner is listed as day-to-day after suffering an apparent right shoulder injury earlier this week.
Leafs head coach Mike Babcock says he doesn't know if the star rookie will be able to play Saturday against Ottawa.
The 19-year-old winger missed practice on Friday morning.
He left a 5-2 loss to the Columbus Blue Jackets on Wednesday evening with an apparent right shoulder injury.
Marner fell awkwardly into the boards in the second period against the Jackets, returning to play two shifts in the third before exiting for good.
He leads the Leafs and all NHL rookies with 48 points this season.
