​The Boston Bruins held a 2-0 lead in the first period of ​Game 4, but the margin wasn't quite that fat for very long. They surrendered an early goal to Columbus Blue Jackets winger Artemi Panarin. Yet, the goal did not come without controversy. 

​​When watching the play, you can see defenseman Seth Jones fire a slap shot towards the net. As the puck careened towards Bruins goaltender Tukka Rask, it ricocheted off winger Oliver Bjorkstrand's stick and into the netting above the glass.


That usually signals a play stoppage. However, the on-ice officials didn't see it, leaving Boston confused, and allowing Panarin to swoop in and put the puck in the net.

Yet another ​controversial moment in these Stanley Cup Playoffs.
