The Islanders are expected to have 12,000 fans at Nassau Coliseum, which would be their largest crowd of the season. They played before 9,000 for their 5-3 win against the Pittsburgh Penguins in Game 6 of the first round May 26.
New York's victory in Game 2 at Boston allowed it to take home-ice advantage from the Bruins, who were 0-3-1 on Long Island during the regular season.
"The Coliseum is a special place, I think, just because so many people have a connection to back in the glory days when they won four straight (championships from 1980-83)," Islanders center Brock Nelson said. "The teams, the players that have come through here, there's lots of history. It's a pretty unique building, I think, the way it's set up and where it is.
"Guys love playing here with a full rink. It should be a good one tonight."
