It's OK for hockey fans to express their hatred toward Penguins captain Sidney Crosby, but when an opposing broadcaster does it in the middle of a game, that's the definition of trouble.
In Game 3 of the Penguins-Flyers series on Sunday, Crosby continued to add more fuel to the fire of this already intense rivalry.
Philadelphia radio broadcaster Chris Therien called Crosby out during the middle of a skirmish, saying "What's to say somebody just can't punch his lights right out, concussion or no concussion?"
Therien expressed his displeasure in Crosby starting the line brawl, continuing by saying "Punch him in the face as hard as you can."
Therien delivered the "absolute joke" comment after Crosby came up to Flyers winger Scott Hartnell from behind, grabbed the back of his sweater and attempted to throw him on the ice.
