Toronto Maple Leafs reveal the nature of Jake Muzzin's possible career ending injury, and it's not good news

The injury was suffered in an October game against the Arizona Coyotes when on a seemingly nothing play, Muzzin collided with Clayton Keller. Muzzin fell to the ice, got up slowly, left the ice and would not return. After the incident Muzzin's good friend Mitch Marner shared some cryptic thoughts, simply hoping his friends day-to-day life would not be impacted by the injury. We know now why.

Elliotte Friedman shared the following details:

A cervical spine injury is nothing to play around with and will likely mark the end of Muzzin's NHL career. A true warrior who won the Stanley Cup with the LA Kings, will be remembered for his rugged style, especially if this is the end.
