At 3:48 of the second period in the Blackhawks/Predators game, Chicago requested a Coach's Challenge to review whether Austin Watson interfered with Blackhawks goaltender Anton Forsberg prior to his goal.

After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed that the incidental contact between Watson and Forsberg did not constitute a goaltender interference infraction.
Therefore the original call stands - good goal Nashville Predators.
Since the Coach's Challenge did not result in the original call being overturned, the Chicago Blackhawks forfeit their time-out.
