SUNRISE, Fla. -- Mike Sullivan didn't have much to say on the way things got a little chippy in the third period of the Penguins' 4-1 loss to the Panthers.
"I just think it's hockey," Sullivan said. "Both teams are emotionally invested."
Where it all began was midway through the third period. Jason Zucker was racing into the Panthers end chasing a puck, trailed by Panthers defenseman Aaron Ekblad. Zucker and Ekblad collided, and when Zucker lurched forward to reach for the puck, he ran into Panthers goaltender Sergei Bobrovsky, who had came out of his net to try to play the puck.
