Coach's Challenge: OTT @ MTL - 3:59 of the First Period

At 3:59 of the first period in the Senators/Canadiens game, Montreal requested a Coach's Challenge to review whether Ottawa's Brady Tkachuk interfered with goaltender Carey Price prior to Colin White'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 Montreal Canadiens forfeit their time-out.
