Chargers start to release players

On the day the San Diego Chargers did not franchise receiver Vincent Jackson, they made another move by releasing defensive lineman Luis Castillo.

A first-round pick in 2005, Castillo broke his leg in the season opener last year and did not play the rest of the season. He made 79 starts for the team and he was a solid member of the defense for several years.

In a team release, general manager A.J. Smith indicated Castillo could perhaps be re-signed. But expect the Chargers and Castillo to both first look to move on.

The Chargers are probably not done cutting former high-profile players. Left tackle Marcus McNeill is expected to be cut this week. He is due a big roster bonus and like with Castillo, cutting him would provide some cap relief. McNeill ended last season on the injured reserve with a neck injury. He has not been cleared medically. The want to re-sign Jared Gaither, who was excellent as an injury replacement for McNeill.
