Castillo's contract could be worth $7.035 million

SAN DIEGO -- Defensive tackle Luis Castillo, one of the San Diego Chargers' two first-round draft picks, agreed to a five-year
contract on Tuesday and was expected to be at the second practice
of training camp.

Castillo's deal is potentially worth $7,035,000, including
guaranteed money of $4,664,000. ESPN.com senior writer John Clayton reports that Castillo's signing and option bonus totals $4.13 million and the deal gives Castillo a base salary of $754,000 in its first year.

"Luis is a competitor and he wanted to be there with his
teammates as soon as possible," said his agent, Mike McCartney.
"It was important to do a good contract, but also to be a Charger

Talks continued with San Diego's other first-round pick, outside
linebacker Shawne Merriman. General manager A.J. Smith said talks
with second-round pick Vincent Jackson have broken down.

Chargers rookies and selected veterans opened camp with a
practice Tuesday morning.

Castillo, taken with the 28th pick, tested positive for
androstenedione at the scouting combine in February. He later said
it was "a huge mistake" in taking the steroid to help his
performance at the scouting combine after he was slow to heal from
an elbow injury sustained his senior year at Northwestern.

Castillo got a signing bonus of $1.38 million and will receive
an option bonus of $2.53 million in March. He'll earn $754,000 his
first season, including a roster bonus of $524,000.
