Auston Matthews didn't finish Thursday's shootout victory over the New York Islanders.
The young Toronto Maple Leafs star left the contest in the final minutes after colliding awkwardly with Islanders forward Cal Clutterbuck.
Matthews went to the dressing room and did not return.
The apparent injury occurred not long after Matthews scored the tying goal with about three-and-a-half minutes remaining in regulation.
Maple Leafs head coach Mike Babcock didn't have an update on his leading scorer when asked about him postgame, stating the club would know more Friday morning, according to Sportsnet's Chris Johnston.
