This is a weird one, so let’s start from the beginning.
There was a quick bit of confusion amongst players before the referee came in to stop the play to make sure Hickey, who had blood on his visor, was OK.
While that was happening, Cal Clutterbuck, who was shadowing Kris Letang at the blue line, apparently didn’t hear the whistle or was upset that Letang, correctly, stopped playing and decided to cross-check him in the arm.
Letang, displeased with the cross-check, returned the favor with a punch that caught Clutterbuck high, sending rhe latter crumbling to the ice.
Clutterbuck struggled to get back up before skating hunched over off the ice. He was called for cross-checking on the play while Letang received a roughing minor.
Clutterbuck did not return to the game.
Hickey, meanwhile, left the game for a brief time before returning.
