After he dropped the puck, the linesman tried to get out of the way and get in position and things went very wrong. Panthers defenseman Aaron Ekblad stepped up to keep the puck in the zone and absolutely leveled the linesman from behind. No one was hurt on the play, but the linesman definitely has a sore back right now.
