FOXBORO - The Patriots now have just one unsigned draft pick following the announcement early Tuesday evening that second-round selection Terrence Wheatley, cornerback out of Colorado, had signed.

No details of the signing were given by the team, but most of the rookie pacts have been for four years in duration.

That leaves linebacker Jerod Mayo, the first-round selection, still not under contract. Picked 10th overall, the Tennessee product still has until Thursday morning to get his first pro contract signed so the Patriots will have a complete contingent on hand for the first practice of the preseason.

Wheatley, 23, was the 62nd overall selection in this year's NFL Draft. He played in 40 games with 28 starts for Colorado over four seasons (2003-04, 2006-07), recording 156 tackles (124 solo), 1.5 sacks, 14 interceptions for 154 yards and two touchdowns, 31 passes defensed, two forced fumbles and two fumble recoveries.

Wheatley also gained 1,350 yards on kickoff returns in his collegiate career. His 14 interceptions tied the second highest total in Colorado history, and he became the first Colorado player in 25 years to record three interceptions in a game when he achieved the feat against Texas Tech.
