At 2:59 of the third period in the Rangers/Lightning game, Tampa Bay 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 confirmed that Tampa's Gabriel Dumont made incidental contact with Rangers goaltender Henrik Lundqvist before the puck crossed the goal line, preventing Lundqvist from doing his job in the crease.
Therefore the original call stands - no goal Tampa Bay Lightning.
Since the Coach's Challenge did not result in the original call being overturned, the Lightning forfeit their time-out.
