Cardinals coach Bruce Arians says he expects first-round draft pick Robert Nkemdeche to be sidelined for two weeks with a high ankle sprain.
The big defensive Arizona tackle was injured in the first day of rookie camp on Tuesday, but Saturday was the first time Arians has given a timeline for the rookie's return.
Cornerback Mike Jenkins, who signed with the Cardinals on July 19, left Friday's first training camp workout with a broken bone in his hand. Arians said there's no prognosis on how Jenkins will be out.
Tight end Jermaine Gresham left practice Friday with a tight hamstring. An MRI is planned but Arians said the injury is not considered serious.
Defensive tackle Red Bryant sat out Saturday's practice with soreness in an Achilles tendon.
