Steelers safety Troy Polamalu won his appeal of a $10,000 fine for using his cell phone on the sideline during a game, according to a league source. He was fined for using his phone during a win over the Jaguars on Oct. 16. Polamalu, who has a history of concussions, had a brief phone conversation with his wife near the bench area after exiting the game with concussion-like symptoms. Possession of cell phones, PDAs or other electronic equipment in the bench area during a game is strictly prohibited by NFL policy beginning 90 minutes before kickoff through the end of the game.
