Toronto's worst nightmare confirmed.

According to RDS, a Swedish radio station has confirmed that Toronto Maple Leafs' prospect and the AHL leading scorer, William Nylander has been placed under observation at a local hospital in Finland.

Nylander has received a vicious high hit during a game between Sweden and Switzerland by Chris Egli. The Swiss forward received a match penalty for his hit on Nylander, who was apparently shaken up after the hit.

The Toronto Marlies' player is leading the AHL with 34 points in 27 games, including 14 goals.

More details to come.
