At 11:50 of the first period in the Kings/Senators game, Los Angeles requested a Coach's Challenge to review whether Brady Tkachuk interfered with goaltender Jack Campbell prior to Chris Wideman'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 Ottawa Senators.
Since the Coach's Challenge did not result in the original call being overturned, the Los Angeles Kings forfeit their time-out.
