"For the second time in a week, a major turnover has affected the San Diego's backfield.

In the same week the Chargers decided to release running back LaDainian Tomlinson, they also opted not to tender running back Darren Sproles, freeing him to leave the team in free agency without any compensation, said a source close to the situation.

Had the Chargers wanted to retain Sproles' rights, they would have had to tender him with an offer of nearly $7.3 million for the coming season by March 4. But San Diego deemed that price too high, giving its running back the chance to test free agency. San Diego still would like to re-sign him, and it could, but it will face competition from other teams."
