At 9:20 of the first period in the Flames/Predators game, Nashville requested a Coach's Challenge to review the "Interference on the Goalkeeper" call that resulted in a "no goal" decision.
After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee determined that the incidental contact outside the crease between Nashville's Kevin Fiala and Calgary's Brian Elliott did not constitute a goaltender interference infraction.

Therefore the original call is overturned - good goal Nashville Predators.
Since the Coach's Challenge resulted in the original call being overturned, the Predators retain their time-out.
