BUFFALO -- Mathew Barzal and Adam Pelech will each be out 4-6 weeks for the New York Islanders. Barzal, a forward, went back to Long Island to meet with doctors after he sustained an upper-body injury during a 2-0 loss to the Columbus Blue Jackets on Wednesday. He did not play in Friday's 4-3 win against the Buffalo Sabres.

The New York Islanders struggled out of the gate this year, but injuries to center Mathew Barzal and D-man Adam Pelech could sink the Isles' playoff hopes in the next month.

The New York Islanders placed forward Mathew Barzal on long-term injured reserve and defenseman Adam Pelech on IR on Saturday because of their respective upper-body injuries. Barzal will be required to miss at least 10 games and 24 calendar days after being placed on long-term injured reserve.
