GIF: Lightning's Stamkos loses cool, punches Canadiens' Emelin after penalty call

Steven Stamkos is struggling to control his emotions as the Tampa Bay Lightning are staring elimination in the face, trailing in Game 4 against the Montreal Canadiens.

The Lightning captain was called for hooking Canadiens defenseman Alexei Emelin early in the second period. Stamkos must have felt Emelin embellished the call - something he let Emelin (and the glass of the penalty box) know with his right fist after the play:

Stamkos' anger towards Emelin could also stem from the Game 3 incident where Emelin inadvertently kneed Stamkos in the head. No matter what set Stamkos off, Tampa Bay needs him using his hands for scoring goals - not punching faces - if the team is going to play another game this postseason.
