In the first period, with just four minutes remaining, New Jersey Devils' captain, Nico Hischer, deflected the puck into the defensive zone when Connor Clifton came in for a hit, making contact with Hischer's head, as shown in the tweet below.
Clifton received a match penalty for the head contact and an additional five-minute penalty for fighting. Following the game, Elliotte Friedman tweeted that Clifton would face a hearing from NHL Player Safety.
