A Bruins and Maple Leafs game wouldn't be complete with a little fireworks, and we got that early after a questionable hit on defenseman Matthew Grzelcyk.

Grzelcyk went awkwardly into the boards behind the Boston net after a hit from Toronto forward Sam Lafferty. Leading to an immediate response from A.J. Greer.

Greer ended up with the extra minor with an instigator penalty but the Bruins killed it off.
