Things got awfully heated in the second period of Game 4. Down 4-1 in the second period, David Perron gave Ben Bishop a slash behind the net as he went to get the puck.
"I was reaching trying to prevent him from playing (the puck), but I don't know," Perron said after the game. "He's 6-(foot)-6. He's a big guy."
Soon after that, as the period came to a close, Jordan Binnington gave Jamie Benn a shove and then skated to Bishop to give him a tap with his stick as he left the ice. Binnington received a penalty for roughing and for slashing, while Benn was hit with an unsportsmanlike penalty.
"I'm not sure how it all escalated. It's playoffs, both teams are heated," Berube said. "It's emotional, things happen."
As the series continues, expect the temperature to keep rising.
