ARLINGTON, Texas -- The Dallas Cowboys have agreed to terms on a four-year contract with fourth-round pick outside linebacker Kyle Wilber.

The only draft pick unsigned is first-round pick cornerback Morris Claiborne.

Wilber, an outside linebacker, will receive a signing bonus of $439,220 and the bonus of Matt Johnson, who agreed earlier Thursday, will be $300,584. They will receive base salaries of $390,000, $480,000, $570,000 and $660,000 over the next four years.

Like third-rounder Tyrone Crawford (calf) and fifth-rounder Danny Coale (foot), Wilber was unable to take part in the organized team activities and the minicamp because of an injury. Wilber had surgery on his right index finger following the team’s May rookie minicamp but he is expected to be cleared in time for July 25 when rookies report to training camp.

Wilber had 13.5 sacks and 35.5 tackles for loss in 43 games (36 starts) at Wake Forest. The Cowboys are hoping he can contribute in pass rushing and special teams’ situations with a larger role in the future with Anthony Spencer and Victor Butler entering the final years’ of their contracts in 2012.

In the past, the Cowboys have waited until the week before training camp to begin negotiations with their draft picks, but the new collective bargaining agreement has made the process much smoother. Over the last four days, the Cowboys have come to terms with six picks, starting monday with Coale, James Hanna and Caleb McSurdy. Crawford signed Wednesday.
