In this situation it looks like a clean
body check was thrown by Chris. Darcy was taken out into the boards while
he was carrying the puck. So, from the original picture, there would
probably be no penalty assessed.
However, from the vantage point of the
referee, who saw what happened from this vantage point, it is clear
that an elbow has landed on Darcy’s neck/face.
From this point of view the Referee would
probably assess an "Elbowing" penalty.
This is what would be
considered an ‘Impact Penalty'.
By calling the penalty it shows both teams that they will not
get away with the high hits to the head of their opponent. It sets the
tone for the rest of the game.
