Darren Sproles, who is expected to sit out minicamp and coaching sessions in May, has yet to sign his franchise tender with the Chargers. Talks between Sproles' agent and the team are ongoing. "I know there are going to be some things that are limited, but I expect him to take part in most of (the offseason)," coach Norv Turner said. "You always want them there, you always want everyone there. But he does a great job of getting himself physically ready. . . . Darren will continue to do that."
