Calle Jarnkrok suffers serious injury during practice.

The Toronto Maple Leafs will be without one of their regulars for quite some time.

On Saturday morning, Toronto Maple Leafs head coach Sheldon Keefe confirmed some terrible news when he revealed that forward Calle Jarnkrok would be out for a few weeks. Keefe revealed that, at some point during practice on Friday, Jarnkrok was involved in an incident that left the 32 year old Swede with a broken knuckle.

It is not clear at this time how Jarnkrok suffered the injury.

According to Keefe, Jarnkrok will now be out on a week to week basis with no firm timeline established for his return just yet.
