At 16:25 of the second period in Predators/Islanders game, New York requested a Coach's Challenge to review whether Nashville's Scott Hartnell interfered with Islanders goaltender Jaroslav Halak prior to Calle Jarnkrok's goal.

After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed no goaltender interference infractions occurred.
Therefore the original call stands - good goal Nashville Predators.
Since the Coach's Challenge did not result in the original call being overturned, the New York Islanders forfeit their time-out.
