At 7:49 of the third period in the Golden Knights/Sharks game, Vegas requested a Coach's Challenge to review whether San Jose's Logan Couture interfered with goaltender Marc-Andre Fleury prior to Evander Kane's goal.

After reviewing all available replays and consulting with the Referee, the Situation Room confirmed no goaltender interference infractions occurred before the puck crossed the goal line.
Therefore the original call stands - good goal San Jose Sharks.
Since the Coach's Challenge did not result in the original call being overturned, the Vegas Golden Knights forfeit their time-out.
