IRVING, Texas - The Dallas Cowboys have signed first-round draft pick Byron Jones to an $8.6 million, four-year deal.

With the signing of Jones on Thursday, the Cowboys have all eight of their draft picks from this year's draft under contract. Jones, a cornerback from Connecticut, was taken 27th overall.

Jones' deal includes $7 million guaranteed with a $4.5 million signing bonus.

It was the second time in four drafts the Cowboys used their first-round pick on a cornerback. Dallas traded up to get Morris Claiborne at sixth overall in 2012. The Cowboys recently declined to pick up the fifth-year option of his rookie contract for 2016.

Claiborne isn't participating in off-season workouts and likely won't be ready for the start of training camp because of a torn patellar tendon in his left knee that kept him out of 12 games last season.
