SAN ANTONIO -- Cowboys starting cornerback Mike Jenkins missed the team portion of drills Monday as he's still recovering from a stinger.
Jenkins, who suffered the injury last week, is still experiencing weakness in the shoulder/neck area.
"I'm getting better," Jenkins said. "But all injuries are frustrating."
Wide receiver Manuel Johnson (concussion) was cleared and started some conditioning.
A MRI result revealed wide receiver Titus Ryan has a bruised bone in his foot and could miss 2-3 weeks. It's the second time Ryan has been in training camp with the Cowboys where he suffered an injury. Last year, he broke his thumb in the Hall of Fame game.
Kai Forath (quad), Teddy Williams (hamstring), Tashard Choice (calf), DeMarco Murray (hamstring), Andre Gurode (knee), Terence Newman (groin), Keith Brooking (hamstring), Bruce Carter (knee) and Jay Ratliff (hip) missed practice.
