It's unclear how Jarnkrok acquired the injury, whether it was earlier in training camp or something that just popped up, but for now he's not going to be on the ice until he recovers. Jarnkrok was set to be a staple on the bottom-6 for the Maple Leafs and is coming off a down year where he only managed 10 goals, but is clearly capable of putting the puck in the net, having scored 20 in 2022-2023 for Toronto. The 11-year veteran has 136 goals and 165 assists for his career spent between Nashville, Seattle, Calgary and of course, Toronto, and offers the Maple Leafs defensive versatility while also being able to score a bit. He's a tad pricey for his output, but it's a blow nonetheless to Toronto.
We will have to wait and see how this injury turns out, but for now all we can hope is it's nothing too serious and Jarnkrok can try and make his way back onto the ice in time to get comfortable for the start of the regular season; the Maple Leafs cannot afford any setbacks on their journey to the Stanley Cup but Jarnkrok could have had just one too many for the team to be comfortable with him.
