Watch: Kulikov pops off Voracek's helmet with late hit

The NHL's Department of Player Safety may want to take another look at this hit, and not just because Dmitry Kulikov managed to pop Jakub Voracek's helmet off.

Rather, the Buffalo Sabres defenseman appeared to levy the check well after Voracek had moved the puck, which could warrant supplemental discipline from the NHL. Kulikov was assessed a two-minute charging penalty on the play.

Voracek left the game for observation, but was able to return.
