Maple Leafs head coach Sheldon Keefe spoke to the media post game in Philadelphia, stating that it doesn't appear to be a shoulder or head injury for Järnkrok, but he will need to be properly evaluated back in Toronto on Friday before Saturday's home game matchup against the Carolina Hurricanes. With the injury not being to his head or shoulder, that leaves neck and collarbone injuries as the most likely scenarios here.
This is unfortunate news for Järnkrok, who has been a consistent top nine contributor in Toronto. He only recently returned to the Maple Leafs' lineup March 2nd from a broken knuckle that had him out of service since January 27th.
With Toronto's cornerstone winger Mitch Marner already injured and Calle Järnkrok now joining him, this gives the opportunity for Nicholas Robertson or Noah Gregor to potentially draw back into the lineup if both Marner and Järnkrok are slated to miss Saturdays game, which appears to be the most likely scenario.
