SAN DIEGO — LaDainian Tomlinson remains with the San Diego Chargers in the hours leading up to NFL free agency and the reopening of the trading period.

General manager A.J. Smith divulged no specifics, but said Thursday that the team is still working to regnegotiate the star running back's contract in an attempt to lower his salary for 2009.

"All I can tell you is everything's ongoing," Smith said. "I've got nothing more to add at this time. But I will add this — we'd love to have him. We hope he returns."

Tomlinson's contract expires after 2011. Trading or releasing the 2006 NFL MVP remains an option for the Chargers.
