Coach's Challenge: FLA @ PIT - 13:36 of the Second Period

At 13:36 of the second period in the Panthers/Penguins game, Florida requested a Coach's Challenge to review whether Pittsburgh's Patric Hornqvist interfered with Florida goaltender James Reimer prior to his 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 Pittsburgh Penguins.
Since the Coach's Challenge did not result in the original call being overturned, the Florida Panthers forfeit their time-out.
