Toronto Maple Leafs management, coaches and its fan base are holding its collective breath right now as it awaits word on the health of the club's top prospect.
Swedish world-junior forward William Nylander, who stars for the Leafs' farm team, suffered an injury Saturday in a game against Switzerland.
Swiss forward Chris Egli levelled Nylander with a shot to the head near centre ice halfway through the first period.
The 19-year-old left the game and has not returned.
Nylander, selected eighth overall by the Leafs in the 2014 NHL draft, is considered one of the main attractions at the Helsinki-hosted championship tournament.
