Life has generally been smiling on the New York Islanders lately.

On the ice, Mathew Barzal continues to rise as a star, including last night’s overtime-winner. The Isles also won a bid to build a new arena at Belmont Park. Correct or not, both developments make people optimistic about John Tavares sticking around beyond this season, the most important development of them all.

Not every headline is a happy one, though.

The Isles’ defense could be in for some serious challenges going forward, as two important blueliners could be sidelined for some time with injuries.

For one thing, around the holiday break, it was revealed that Calvin de Haan might need to undergo surgery, threatening to end his season. Today brought another unfortunate development, as the Islanders announced that Johnny Boychuk is considered week-to-week with a lower-body injury.
