Chargers release veteran DE Castillo
The seven-year veteran was a standout for the Chargers for much of his career, starting 79 of the 82 games he played, with 276 tackles, including 43 for a loss and 19 sacks.
But he broke his left leg in the 2011 season opener and didn't play again.
A first-round draft pick in 2005, Castillo signed a one-year, $1 million contract with the Chargers in April after visiting Kansas City and New England. Now he is an ex-Charger.
