Coach's Challenge: STL @ BOS - 3:23 of Second Period

At 3:23 of the second period in the Blues/Bruins game, Boston requested a Coach's Challenge to review whether Jori Lehtera interfered with Bruins goaltender Tuukka Rask 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 Boston Bruins forfeit their time-out.
