Thatcher Demko's injury finally revealed.

The mystery surrounding what exactly is going on with Vancouver Canucks star goaltender Thatcher Demko is finally over. Although the Canucks themselves have not been very forthcoming about what exactly is going on with their number one goalie, a report on Monday morning has finally shed some light on the situation.

That news was broken on Monday morning by the National Hockey League's own Kevin Woodley, when he was a guest on Sportsnet's Halford & Brough earlier today. Woodley would reveal that the injury Demko suffered is to his Popliteus, a deep muscle of the knee joint.

"There is no longer uncertainty about what it is," revealed Woodley this morning. "So you guys can get your WebMD out and look up Popliteus, it is a thin triangle shaped muscle behind the back of the knee. That evidently is where the injury occurred."

Although the muscle isn't a very big one, it does play an important role in the knee joint.

"It is a small but somewhat significant stabilizing muscle," said Woodley.

What has complicated the situation for Demko is that this appears to be an extremely uncommon injury, leaving a lot of question marks surrounding the injury even when it comes to the medical experts.

"It is super rare," admitted Woodley. "I've talked to a couple of people that have been doing this at the NHL level for 30 years, they've never seen it."

For that reason, the Canucks have likely been forced into taking a wait and see approach to this injury, with no history of player recovery to draw from or even point to.

"There's obviously uncertainty that comes when there's no prescribed way to improve it." admitted Woodley.

That doesn't seem to be exclusive to those experienced in the areas of the NHL either, with even a quick google search showcasing how much uncertainty there is around an injury of this nature according to Woodley.

"When you first look it up one of the first things you'll see is the healing time is anywhere from 3 to 16 weeks," said Woodley with a laugh. "Nothing like nailing it down right? There is that much uncertainty with that injury."
