Defensive end Calais Campbell agreed to terms on a four-year contract Monday, leaving Dominique Rodgers-Cromartie as the only unsigned rookie.

And then there was one.

Defensive end Calais Campbell, the Cardinals' second-round draft pick, agreed to terms on a four-year contract Monday, leaving just top pick Dominique Rodgers-Cromartie without a contract from the team's 2008 draft class.

Already at the 80-man roster limit, the Cardinals released defensive end Bo Schobel to make room for Campbell.

Negotiations with Rodgers-Cromartie have been ongoing and without any significant hitches thus far. The team is still hopeful a deal can be struck with the cornerback before the players report for an evening meeting Wednesday in Flagstaff.

Once Rodgers-Cromartie signs, the team will have to release another player.

As usual, the Cardinals did not disclose the details of Campbell's contract.

Campbell, a 6-foot-8, 282-pounder out of Miami (Fla.), dropped in the draft after a disappointing junior season. But the Cardinals see the potential as a good fit in their 3-4 defensive looks and an ability to make a difference at the left end spot in which Darnell Dockett turned in a Pro Bowl season a season ago.

Campbell is also part of the significant depth the Cards attempted to add to the defensive line in the offseason, after the unit wore down as 2007 went on. Not only did the Cardinals draft Campbell, Iowa defensive end Kenny Iwebema and Texas A&M end-turned-linebacker Chris Harrington, but they also brought in veteran free agents Travis LaBoy and Bryan Robinson.

EXTRA POINT: The agent of both Anquan Boldin and Darnell Dockett, Drew Rosenhaus, told the Arizona Republic his clients plan to report on time for training camp despite their desire for new contracts. Both Boldin and Dockett skipped all the offseason voluntary organized team activities over the issue.
