The Oakland Raiders have agreed to terms on a three-year contract extension with cornerback Stanford Routt, a source with knowledge of the situation said Thursday.
Routt will earn a maximum of $31.5 million during his contract, including $20 million over the first two years, according to league sources.
The deal places him in the upper echelon of cornerbacks (Champ Bailey's new contract averages roughly $11 million per season, for instance). Securing Routt at this rate could further lessen Oakland's ability to give Asomugha the type of top-of-the-market deal he will command.
Routt had 55 tackles and made two interceptions, returning one for a touchdown in 2010.
"Stanford Routt is in his prime," senior executive John Herrera told The Associated Press. "He's a young, 27-year-old veteran who already has six years of experience in the league. He's one of the fastest cornerbacks in the league, and his best years are still ahead of him."
Routt was one of three deals the Raiders made on the defensive side of the ball Thursday. The team agreed to a two-year, $8 million contract with defensive tackle John Henderson, a person with knowledge of the deal told the Associated Press. The Raiders also placed the franchise tag on linebacker Kamerion Wimbley.
Henderson had 30 tackles in nine games last season for Oakland while being limited by a foot injury. The two-time Pro Bowler in Jacksonville played mostly as a reserve to shore up the run defense in his first season in Oakland last year.
The Raiders have been in contact with tight end Zach Miller during the past few days to explore options for re-signing him, according to league sources. Franchising Miller remains an option as well by Thursday's 4 p.m. ET deadline.
Miller led the Raiders with 60 receptions and five touchdown catches.
