Penguins' Sullivan refuses comment on Callahan avoiding discipline

Pittsburgh Penguins head coach Mike Sullivan is playing coy. Either that, or he's incredibly focused on Game 2.

In Game 1 of the Eastern Conference Final, Tampa Bay Lightning forward Ryan Callahan drove Penguins defenseman Kris Letang head-first into the boards.

Callahan was assessed a five-minute major, and was thought to be the target of the NHL Department of Player Safety, but reports indicate the Lightning forward won't be suspended.

Sullivan is adamant on leaving the incident in the past.

"I don't have any thoughts or observations," Sullivan said, according to Sportsnet's Chris Johnston. "We're just going to play hockey."

Friday's Game 1 had no shortage of fireworks, and expect the same Monday in Game 2.
