Pryor was hurt during a kickoff return Saturday and is going through the NFL-mandated protocol on head injuries. He must be cleared before he can return to practice. Pryor was on the field Tuesday and stretched before practice, and then worked with trainers.
Second-rounder Jace Amaro was limited. The tight end tweaked his right knee, which has tendinitis, on Sunday and practiced briefly Tuesday before spending the rest of practice on the sideline.
Also among those who didn't finish practice were: wide receiver David Nelson (groin), running backs Bilal Powell (hamstring) and Alex Green (chest), cornerback Ras-I Dowling (foot) and tight end Colin Anderson (thumb).
