An injury will likely keep a Calgary Flames prospect from appearing at this year’s World Junior Championship tournament over the winter holidays. Per a report from HockeyNews.se, all indications are that forward Theo Stockselius won’t be available to represent Sweden at the upcoming World Juniors in St. Paul and Minneapolis, Minnesota, running Dec. 26 to Jan. 5.
One of the youngest players in his draft class as a July birthday, the 18-year-old Stockselius was a second-round selection by the Flames in last June’s NHL Draft. Despite dealing with a thyroid cancer scare a few years back, Stockselius has emerged as one of the most exciting young players in Swedish hockey based on his size, skill and versatility.
Based on his prior experience with Sweden’s national under-18 team at last spring’s Under-18 Worlds it seemed like Stockselius would have a good shot at their World Junior roster. He appeared at the 5 Nations international event in August and impressed, but he suffered a cut from a skate in a U20 Nationell game back on Oct. 8 and was forced to miss the November instalment of 5 Nations action, typically used by the Swedish national team as a preparation camp for World Juniors.
Here’s some of what HockeyNews.se’s Mattias Ek reported, via Google Translate:
Stockselius, who was drafted by NHL club Calgary, is reported to be doing well during rehab training.
– Pretty okay, I think. He got that nasty injury and after that he had to turn down the junior national team, which was unlucky for him. He is rehabilitating and slowly but surely getting better and better, says Djurgården’s sporting director Niklas Wikegård to Hockeynews.
According to Wikegård, there will probably be no JVM game for Theo Stockselius, who was born in 2007. Given his young age, he may get another chance next season.
(JVM is the Swedish translation WJC, the English acronym for the World Junior Championship.)
In other words: Stockselius is progressing in his recovery, but it’s unlikely that he’ll be back playing games with his club team prior to Sweden’s World Junior camp in early December.
It’s disappointing. But given that Stockselius will also be eligible for next year’s World Juniors, coincidentally being held in Alberta, he’ll have another chance at representing his country in the future.
