Nolan Patrick will miss out on an opportunity to play at the 2017 IIHF World Junior Championship.

Hockey Canada announced in a tweet Monday night that Patrick, first overall in Future Considerations’ Fall ranking for the 2017 NHL Draft,  has not been medically cleared to attend their National Junior Team Sport Chek Selection Camp and will not play at the World Juniors.

Canada’s camp will run from Dec. 10-14 in Blainville, QC.

Patrick, who has four goals and nine points in six games this season,  has not played since Oct. 11 because of an upper-body injury.

“He’s working at it every day,” Wheat Kings coach David Anning told Future Considerations on Nov. 18. “He’s trying to get back into the lineup. As it stands right now it remains an unknown. Unfortunately I don’t have more information other than it remains day-to-day.”

The 18-year-old was named WHL rookie of the year in 2014-15, and had 41 goals and 102 points in 72 regular season games for Brandon in 2015-16. He added 13 goals and 30 points in 21 games en route to helping Brandon to the Ed Chynoweth Cup as WHL champions.

No replacement has been named for Patrick.
