Source: Rolle will test free-agent market

Arizona's eventful offseason will continue this week when the Cardinals release former first-round pick Antrel Rolle, an NFL source said Sunday.

Rolle's release will follow Kurt Warner's retirement and the Cardinals decision not to use their franchise tag on linebacker Karlos Dansby.

Rolle will become the premier safety in this year's free-agent class, but it is still possible the safety will return to the Cardinals.

Arizona would like to have Rolle back, and the two sides continue to talk about a potential return.

With less than a week until the start of the March 5 free-agent signing period, Rolle wants to see what he's worth at a time when the Cardinals are reluctant to pay him more than the $12 million that would be owed to him this season.

Rolle had four interception and was a Pro Bowl alternate this season. A starter on the Cardinals' Super Bowl team, Rolle moved to free safety in 2008 after playing cornerback for his first three seasons. He has 12 interceptions and four touchdowns in his career.
