Alex Smith officially signed with the San Francisco 49ers yesterday and other first-rounders began to fall into line as teams prepared to open training camps.

The former Utah quarterback, the first overall pick in April's draft, put his name on a $49.25 million deal that could be worth as much as $57 million with incentives. It includes $24 million in guaranteed money.

"Now it's time for me to go earn this money and prove that I deserve this money," said Smith, who will try to take the 49ers' starting job from Tim Rattay. "The primary goal is to get on the field. I don't think this team is paying me this money to sit on the sideline."

Smith agreed to terms on Monday with the 49ers. Two players at the bottom of the first round, offensive linemen Logan Mankins of New England and defensive tackle Mike Patterson of Philadelphia, signed Monday.

* CARDINALS: Arizona is moving its training camp south 78 miles from Flagstaff to Prescott after a viral outbreak on the Northern Arizona University campus, where the team normally stays.

The decision to move was made Monday, and after a quick bus tour by team officials, Prescott was chosen as the new site yesterday. The Cardinals already planned a three-day extended training camp there Aug. 24-26.

The camp will open as scheduled, with players gathering on Sunday and the first workout on Monday.

* CHARGERS: Defensive tackle Luis Castillo, the 28th overall draft choice, agreed to terms with San Diego. Castillo's deal is potentially worth $7,035,000, including guaranteed money of $4,664,000.

* JAGUARS: Jacksonville signed its sixth-round pick, wide receiver-return man Chad Owens. Details were not available.

* RAIDERS: Oakland signed its top draft pick, cornerback Fabian Washington, the 23rd overall choice, to a five-year, $7.8 million contract, including a $5 million bonus, and added three free agents three days before the team's first training camp practice. Oakland signed free agent safety Calvin Branch and defensive tackles Lorn Mayers and Michael Quarshie.

* RAMS: St. Louis re-signed veteran guard Tom Nutten, who came out of retirement last year to help the team for whom he started in its Super Bowl-winning season of 1999.
