The NHL is taking a look at an incident that occurred during warmups ahead of Game 3 between the Toronto Maple Leafs and Ottawa Senators.

OTTAWA -- Simon Benoit scored at 1:19 of overtime to give the Toronto Maple Leafs a 3-2 win against the Ottawa Senators in Game 3 of the Eastern Conference First Round at Canadian Tire Centre on Thursday. Auston Matthews won a face-off in the left circle back to Benoit, whose slap shot beat Linus Ullmark through traffic.

The Senators got on the board first with a Claude Giroux goal on the power play in the second period. Matthew Knies knotted the score at 1-1 with a goal before the second intermission. Matthews put Toronto ahead for the first time early in the third period before Brady Tkachuk leveled it all up at 2-2 with an even-strength goal.
