Nelson tallied both of his goals in the second frame. First, he found the back of the net on a wrist shot in the slot off a pass from Maxim Tsyplakov and Adam Pelech.

Nelson scored the second goal of the game for the Islanders, redirecting a long shot from Adam Pelech to give New York a 2-0 advantage. That goal accounted for the 250th of his career.
