Toronto Maple Leafs fans held their collective breath Thursday night, and not just because of the possibility of the club clinching a playoff berth.

Auston Matthews took a knee-on-knee hit from Tampa Bay Lightning defenseman Jake Dotchin after entering the offensive zone late in the first period.

The Leafs phenom's parents were in the building, and their reactions were exactly as you'd expect.

Leafs fans - and the Matthews family - would eventually exhale, as Matthews came back out on to the ice shortly thereafter.
