The Chargers changed their mind on Darren Sproles, opting Thursday morning to place a first-and-third tender on the dynamic running back and kick returner. Jamal Williams, a Pro Bowl nose tackle who had been with the Chargers for 12 seasons, was released. He will be 34 next month, would have been owed a $1 million roster bonus and was scheduled to earn $5 million in 2010.
