At 16:29 of the third period in the Devils/Penguins game, Pittsburgh requested a Coach's Challenge to review whether a New Jersey player interfered with Pittsburgh goaltender Matt Murray prior to Kyle Palmieri's goal.
After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed no goaltender interference infractions occurred before the puck crossed the goal line.

Therefore the original call stands - good goal New Jersey Devils.
Since the Coach's Challenge did not result in the original call being overturned, the Pittsburgh Penguins forfeit their time-out.
