Former first-round pick Darius Robinson has had a major role on the Arizona Cardinals' defense early in training camp after a difficult rookie year.

The Arizona Cardinals announced some roster moves on Sunday ahead of their practice in front of just season ticket-holders. They placed cornerbacks Star Thomas V and Jaden Davis on injured reserve with knee injuries and added a cornerback with the last name of Gilmore.

On Friday, a cornerback battling for a starting job fell awkwardly and was carted off near the end of practice.
