Coach's Challenge: CHI @ STL - 17:49 of Third Period

At 17:49 of the third period in the Blackhawks/Blues game, Chicago requested a Coach's Challenge to review whether Jori Lehtera interfered with goaltender Corey Crawford before the puck entered the net.
After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed no goaltender interference infractions occurred before the puck crossed the goal line.

Therefore the original call stands - good goal St. Louis Blues.
Since the Coach's Challenge did not result in the original call being overturned, the Chicago Blackhawks forfeit their time-out.
