The Chargers have released defensive end Luis Castillo. During Castillo’s seven seasons in San Diego, he started 79 of 82 games played and recorded 276 tackles, including 43 for a loss and 19 sacks. In 2011 Castillo fractured his left tibia in the Sept. 11 opener versus Minnesota, and was inactive for 11 games before being placed on “Reserve-Injured” Dec. 8. Castillo joined the Chargers as a first-round selection (28th overall) in the 2005 NFL Draft.
