Neither has practiced during training camp. Flanagan has been hobbled by tendinitis in his left knee and Wahle has been pained by a bruised left knee.
"I'm going to be very, very, very conservative with them in getting them on the field," Sherman said after Friday morning's practice. "They're both anxious. They both want to get out there. But, I'm going to play this card all the way to ... whatever the doctors tell me. I''ll probably wait another week."
Speaking of out-of-action offensive lineman, 6-foot-9 offensive tackle Brennan Curtin made his first appearance of training camp but did not practice. The second-year player is on the PUP list due to a three-quarters inch boil that developed into a contagious staph infection. Because of the nature of the infection, Curtin has not been able to spend time with the team.
The Packers, meantime, gained one starting cornerback but lost another. Al Harris returned after missing Thursday with a hip flexor. Out, however, was Michael Hawthorne due to a sprained left ankle. Rookie cornerback Joey Thomas (knee), safety/cornerback James Whitley (concussion) and cornerback Chris Johnson (stress fracture and on PUP) remained out of action, and were joined by cornerback James Horton, who was shaken up after a collision during the morning practice.
The injury-ravaged defensive backfield did get back starting safety contender Mark Roman, who missed some time with a sprained toe and ankle.
Quarterback Tim Couch was limited in Friday's first practice and sat out the afternoon session with a sore arm, most likely stemming from the high number of reps he's taken during this first week of camp. Couch figures to be ready for Saturday's scrimmage and play a large role if he's up to it.
"It depends on how his arm feels," Sherman said. "I'm not going to put him at risk."
