Chargers re-signed NT Ogemdi Nwagbuo.
Luis Castillo is in danger of missing at least half of the season with a broken tibia, so the Chargers brought back a familiar face. Nwagbuo, 25, can play both nose tackle and left defensive end in the 3-4. He appeared in 15 games without a start last season, racking up 19 tackles and a half-sack.
