Auston Matthews potentially dealing with a concussion per new reports

"For whatever reason, it's not one of those everyday types of illnesses that sort of come and go. This one has lingered, and the effects have lingered and gotten worse when he's on the ice asserting himself."

"I know that Matthews has sustained at least two concussions during his years in the NHL. And, while I have no pertinent info, the fact the Leafs are calling it an ‘illness' rather than an injury — and that the issue is complicated by physical exertion — leads me to think he may have taken another shot to the head.

Of course, the NHL has strict concussion protocol and the Leafs would be obligated to keep Matthews out of the line–up if he's experiencing any effects of post–concussion syndrome. I'm sort of debunking my own argument, but no one tells the truth in the playoffs. So we are left to speculate. And, I'm comfortable with the head–shot hypothesis."

"Were that the case, he'd be very sick for a brief time. Food poisoning doesn't ‘linger'. Neither is it exacerbated by physical activity. You find yourself bent over a toilet until it passes."
