Kyle Okposo scored the tying goal on a power play late in regulation and then netted the decisive tally in the shootout for the New York Islanders, who rallied past Philadelphia 4-3 Monday to earn a rare win over the Flyers.

The Islanders used a dominant third period to erase a 3-1 deficit and force overtime.

Brock Nelson made it a one-goal game at 8:16, and Okposo tied it with 2:58 left in regulation on a lunging push with his stick after the puck struck his skate. The goal was confirmed by video replay.

Frans Nielsen and John Tavares also scored in the four-round shootout against Ray Emery, who made 40 saves through overtime.

Anders Nilsson turned aside Vincent Lecavalier and Sean Couturier in the tiebreaker to help the Islanders avoid a four-game, season-series sweep versus the Flyers.
