The Raiders agreed to a three-year deal with cornerback Nnamdi Asomugha, making him the highest-paid defensive back in NFL history.
NFL.com reports the deal is worth a minimum of $45 million and could max out at $50 million with $28.5 million guaranteed in the first two years.
Per NFL.com, if the Raiders choose to keep Asomugha for the third year of the deal he would be paid the average of the top five highest-paid cornerbacks or $16.875 million - whichever is greater.
If the Raiders don't want to pay Asomugha that much, he would become a free agent and the Raiders could not use the franchise tag on him.
The Raiders franchised Asomugha in 2008, something Asomugha did not want this year.
Asomugha's new agent, Tom Condon, who also negotiated the deal for Raiders punter Shane Lechler, brokered the deal.
Lechler's four-year, $12 million contract was a record for punters.
