UNIONDALE - One developer hopes to keep the Islanders playing at the Nassau Coliseum even after they move to Brooklyn's Barclays Center.

Developer Bruce Ratner wants the Islanders to play six regular season games at the Coliseum, along with some preseason games. A Newsday source says that the plan is unprecedented.

"No one has ever requested a team to be allowed to play regular-season games in a second arena in a market where another team has clear territorial rights," the source said.

The New York Rangers, who settled in the New York City area before the Islanders were created, have those territorial rights, but did not exercise them when the Islanders entered the league in 1972, or when they decided to move to the Barclays Center last year.

The game combination is a key component in Ratner's $229 million bid to redevelop the Nassau Coliseum.
