At the 3:30 mark, a 5-on-5 brawl breaks out off the faceoff. Mike Fornabaio at the CT Post breaks down the action:
[sny-box]Nino Niederreiter served the extra minor and, coming out of the box, was called offside on a two-on-one with Sean Backman. Off the draw, Dalton Smith went after him. Mike Halmo tried to jump in between. And all hell broke loose. When Halmo and Smith broke free throwing at each other, other players paired off. Dalton Prout came out of the pile with Niederreiter, who covered himself up as Prout waited, guns cocked. [/sny-box]
Later on in the game, Brandon DeFazio got dumped pretty hard behind the Springfield net (4:45 mark) and that started another fracas. All five guys paired up but only one serious fight came out of it.
