UNIONDALE, N.Y. — John Tavares, Matt Moulson and rookie Michael Grabner all scored their 20th goal of the season and the New York Islanders got some revenge against the injury-depleted Pittsburgh Penguins with their sticks and their fists in a fight-filled 9-3 victory on Friday night.

Just nine days after Brent Johnson beat New York 3-0 and knocked out Rick DiPietro in a one-punch fight that left the franchise goalie with broken bones in his face, the Islanders responded with four goals in the first period and four more in the second — with an all-out brawl in the middle of the offensive outburst.

That was just the appetizer for a third-period donnybrook — in which Johnson fought again — that caused a delay of about 15 minutes. With multiple ejections, both benches had only a handful of players on them for the final 12-plus minutes.
