The Eagles traded sixth round draft pick Charles Scott to the Cardinals for cornerback Jorrick Calvin, who was taken one spot later in April's draft.
Calvin, 5-foot-11, 184 pounds, had 76 tackles, two interceptions and nine pass break ups for Troy as a junior in 2008. He missed his senior season because he was academically ineligible. Calvin and Scott were both seen as firmly on the roster bubbles with the Cardinals and Eagles.
"This guy has return ability ... and you’re always looking for corners," said Eagles general manager Howie Roseman. "It’s a hard to find position. We felt like it was an opportunity to bring a guy in and see what he has ."
The Cardinals also needed a fullback after Nehemiah Broughton tore his anterior cruciate ligament in a preseason game Saturday. The injury left the team with just one fullback.
Scott, drafted as a halfback, had disappointed and was moved to fullback during preseason. Scott was drafted 200th overall. Calvin went 201st to Arizona.
Calvin will add another contender to a position that has already been bolstered by the strong preseason play of rookie Trevard Lindley and Dimitri Patterson.
In injury news, left guard Todd Herremans is not expected to practice Monday after spraining his right ankle Sunday.
Defensive end Trent Cole downplayed his ankle sprain and said he is aiming to play in the Sept. 12 opener. He said the injury, suffered against the Chiefs Friday night, was extremely painful and made him fear for his season, but that he felt relieved after an MRI showed it to be less serious that first feared.
Defensive end Juqua Parker, who sat out Friday's preseason game, was headed out to practice this afternoon. He had returned on Sunday.
