Castillo returns to Chargers

The San Diego Chargers may add a defensive lineman at some point during the NFL draft later this month, but there's less urgency to do so, now that defensive end Luis Castillo is coming back to the team. After getting released last month, Castillo agreed to a one-year deal with San Diego today. The contract is worth $1 million with an added $1 million incentive for playing time.

Castillo was the 28th overall pick in the first round of the 2005 draft. He's made 79 starts in seven years, posting 211 tackles and 19.5 sacks. He missed most of last season after suffering a tibial plateau leg fracture in Week 1 against the Minnesota Vikings.

It's unclear how Castillo will fit into the defensive end rotation, which includes 2011 first-round pick Corey Liuget, Vaughn Martin, Jacques Cesaire, and Damik Scafe. As of right now, it seems as though most believe Liuget and Martin will start. Nevertheless, bringing Castillo back doesn't hurt the Chargers at all. His experience brings stability to the position.
