Linebacker Cody Brown agreed to a four-year contract Tuesday.

The Cardinals and second-round draft pick Cody Brown agreed to a four-year contract Tuesday, leaving just No. 1 selection Beanie Wells unsigned with the team scheduled to report to training camp Wednesday.

As per team policy, terms were not disclosed.

To make room for Brown on the roster, the Cardinals released undrafted rookie cornerback Tony Davis.

General manager Rod Graves said Monday night that negotiations were ongoing with Wells although there were still hurdles to overcome. As of Tuesday morning, only four of the NFL's 32 first-round draft picks had come to agreements with their teams, although that includes the pick right after Wells, Steelers defensive tackle Evander Hood.

The other three signed first-round picks are quarterbacks Matt Stafford (No. 1 to the Lions) and Mark Sanchez (No. 5 to the Jets) and center Alex Mack (No. 21 to the Browns).

The Cardinals report to Flagstaff for training camp Wednesday afternoon, but have a conditioning test Thursday. The first practice isn't until Friday morning, leaving time to still get Wells done without it costing him field time.

Field time will be important to the running back, who was unable to take part in any of the organized team activities because of the NFL rule prohibiting players to practice while their college's current session ends. As a result, Wells has just had the five minicamp practices as on-field work. Wells will compete with Tim Hightower for the starting job.

Brown will have no such issues now, a key point given that he is transitioning from college defensive end to linebacker and is facing a steep learning curve. But the Cardinals are counting on Brown bringing his collegiate pass rushing skills – he had 24 sacks, including 11 in 2008 – to an aging pass-rushing unit.
