The goal of the Islanders playing games at the Nassau Coliseum before moving into a new arena at Belmont Park took a step toward reality Tuesday when NHL commissioner Gary Bettman and a group of senior officials toured the team’s old home with owner Jon Ledecky. Bettman previously had said the Coliseum was not a “viable option” for the Islanders, but now the organization is waiting to hear back about the possibility. “This is in the hands of the National Hockey League, which has to make an assessment of any arena games will be played in,” Ledecky said Wednesday morning on WFAN’s Boomer & Gio. “I’m confident that something will be worked out, yes.” Last month, the Islanders won their bid to build a new arena at Belmont Park but could be looking for a home in the interim. They will continue to play at Barclays Center through the rest of this season and next year, and while Ledecky said Wednesday they “want that shovel in the ground as soon as possible” at Belmont, they could be looking for a home in the season before the new arena is ready.
