Letang had words with the Capitals bench before returning to his own, where he threw a water bottle onto the ground.
"I didn't see the replay. I got hurt pretty bad there in the head," Letang said. "I don't know what clipped me, but certainly something hit me … They were saying that I was staying down for no reason or something. That stuff happens. The chirping."
Although tempers have flared throughout the past two games, Letang thinks most of what has transpired has been no different than what is usually seen during a Stanley Cup Playoff series.
"It's playoff hockey right now. Nobody wants to give up any inches," Letang said. "In front of the net, you'll take a punch. You're going to take slashes. That stuff happens."
The Penguins have been outhit 132-75 through three games. Letang isn't bothered by the physical nature and has no problem continuing.
"The physical part is fine," Letang said. "I just think there's stuff after the whistle. There's stuff behind the play, but for the physical part, that's fine. It's the playoffs."
Letang was suspended one game by the NHL's Department of Player Safety on Tuesday.
