SAN DIEGO — Chargers first-round draft pick Antoine Cason has signed a five-year deal worth $12 million, assuring he will be in camp when the team holds its first full-squad practice on Friday.

"It's a big relief," Cason said. "Of course I was concerned but I had faith that it would get done. All I could do was work out and control the things I was able to control and that was that. I didn't worry about it too much because I knew it would get done, so I did the things I could control."

Cason was the team's last draft pick to sign. He missed three days of rookie camp.
