At 8:11 of third period in the Lightning/Senators game, Ottawa requested a Coach's Challenge to review the "Interference on the Goalkeeper" decision that resulted in a "no goal" call.

After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee determined that the incidental contact outside the crease between Bobby Ryan and Louis Dominguedid not constitute a goaltender interference infraction.
Therefore the original call is overturned - good goal Ottawa Senators.
Since the Coach's Challenge resulted in the original call being overturned, the Senators retain their time-out.
