If the New York Islanders are going to advance past the Florida Panthers, they'll have to do so without Jaroslav Halak.

Head coach Jack Capuano confirmed Tuesday that Halak won't be available for the Islanders' first-round series, as he's still recovering from a groin injury suffered in March.

In Halak's absence, New York started Thomas Greiss, who endured a minor injury down the stretch, as well. Greiss was solid for the Islanders this season, posting a 23-11-4 record with a 2.36 GAA and .925 save percentage.

The Islanders went 9-6-2 after Halak's injury.
