Coach's Challenge: PHI @ BUF - 18:02 of Second Period

At 18:02 of the second period in the Flyers/Sabres game, Buffalo requested a Coach's Challenge to review whether Wayne Simmonds interfered with Robin Lehner prior to Claude Giroux's goal.
After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed that the incidental contact outside the crease between Simmonds and Lehnerdid not constitute a goaltender interference infraction.

Therefore the original call stands - good goal Philadelphia Flyers.
Since the Coach's Challenge did not result in the original call being overturned, the Buffalo Sabres forfeit their time-out.
