The brothers of Arizona defensive end Calais Campbell and quarterback John Skelton are among the 21 undrafted rookie free agents who have agreed to contract terms with the Cardinals.

Jared Campbell was a part-time starter at safety for Miami last season. Stephen Skelton was a tight end at Fordham, the same school his brother attended.

Also on the list are USC center Kris O'Dowd — a high school standout in Tucson — linebackers Kendall Smith of Florida State and Duke Lemmens of Florida, BYU safety Andrew Rich, defensive tackle Ricky Lumpkin of Kentucky, guard Jake Virmiglio of North Carolina State and offensive tackles Eric Mensik of Oklahoma, Brad Thorson of Kansas, Jason Speredon of BYU, and D.J. Young of Michigan State.

The players report to the team's facility in Tempe on Thursday, then move to the training camp in Flagstaff on Friday, with the first practice there on Saturday.
