The deal includes a club option for a fifth season.
Claiborne was the sixth overall pick in the 2012 draft. The Cowboys traded up from the No. 14 spot in a deal with the Rams to acquire Claiborne, the top cornerback in the draft according to NFLDraftScout.com ratings and an All-American at LSU in 2011.
Claiborne and free-agent addition Brandon Flowers -- who signed a
$50 million deal after a breakout season with the Chiefs -- are likely to start in an overhauled Cowboys secondary. Dallas also has veteran Mike Jenkins to boast a strong trio at the position.
Claiborne has recovered from wrist surgery and is not expected to have limitations in training camp when the Cowboys report July 29.
Dallas agrees with Claiborne
