Defensive end Kenny Iwebema, the Cardinals' fourth-round draft pick out of Iowa, agreed to a three-year contract on Monday.

The Cardinals continued their early efforts to sign their draft picks Monday, when fourth-round draft pick defensive end Kenny Iwebema agreed to a three-year contract.

As usual, financial terms were not disclosed.

Fifth-round pick Tim Hightower, a running back, got his deal done last week.

"We knew it was going to get done," Iwebema said. "Right now, everything is focused on football and getting in my playbook and these defenses I have to know -- making things second nature so I don't have to think, 'Where do I have to be?' or ask somebody. I don't like that. I want to be able to help somebody else."

Iwebema was the second of two defensive linemen the Cards selected, after defensive end Calias Campbell was taken in the second round. The 6-foot-4, 274-pounder from Iowa has a history with Cardinals defensive line coach Ron Aiken, who coached Iwebema in college.

Iwebema had his sack totals dwindle his final two years of college, from 7 as a sophomore to just 6½ total his final two years as a Hawkeye, but Aiken said that had much to do with opposing offenses focusing their blocking on Iwebema.

Iwebema acknowledged he missed Aiken's tutelage once Aiken joined the Cardinals' staff last season.

Iwebema is battling for a spot as a reserve defensive end behind Antonio Smith and Darnell Dockett, alongside Campbell, both Bryan Robinsons, and Jason Banks. Iwebema is working at the right defensive end behind the starter Smith.

The Cardinals returned to the field Monday for their fourth and final week of organized team activities.
