According to the GM of the Maple Leafs, defenseman Jake Muzzin will remain on LTIR for the remainder of the season and likely his career. He is suffering from a long-term spinal injury and the odds are against him playing in the NHL ever again.
Muzzin has played 683 games in the NHL between the Los Angeles Kings and Maple Leafs. In his career that spanned over a decade, he won a Stanley Cup with the Kings in 2014 and was an integral part of both franchises for many years.
