The Toronto Maple Leafs are a perfect 5 and 0 without Auston Matthews in the lineup this year. That's the good news.
The bad news is that Matthews is out of the lineup right now, and Mike Babcock is remaining "tight-lipped" about the nature of the injury, according to TSN's Darren Dreger.
“He’s got an upper body … whatever,” Babcock said, according to Lance Hornby of the Toronto Sun.
Babcock has made it clear that he won't disclose the exact nature of a player's injury, rather, designating the descriptor "upper-body" or "lower-body", to avoid having opposing teams targeting specific areas in the hopes of re-aggravating something.
In Matthews' case, he had his head rung when he collided with teammate Morgan Rielly on Saturday against the Pittsburgh Penguins. He was clutching his head, and clearly in some discomfort. He finished the game and wasn't taken off by the concussion spotters, so hopefully it isn't a concussion.
That being said, there are examples around the NHL where a player took a hit to the head and the spotters didn't evaluate it, only to find out days later that a concussion was indeed suffered.
The hope is that Matthews will be available to play this week, but as of now, we don't know exactly what's wrong with him.
