Beat writer Kevin Acee confirms that the Chargers aren’t interested in bringing back free-agent RB Darren Sproles. He’ll be 28 years old when the 2011 season kicks off, and any chance he had of taking on a feature back role is probably gone. Look for Sproles to sign on as a 3rd-down back and return specialist — the same role he served in San Diego. We keep hearing that the Dolphins are interested.
