Danila Zhernov has the puck on his stick, and hugging the boards he brings it deep into the Armada zone. His pass to the slot is intercepted by Wang, who ices the puck.

Shepard wins the ensuing face-off in the Armada zone, but the referee has his arm up and signals a roughing penalty against Augustus Wang.

In the replay, we can see that as the linesman drops the puck, Wang and Eriksson seem to be talking and Wang punches Eriksson in the face. It'll put the Armada on the penalty kill, when they'd rather be looking for a goal to tie the game.
