SANTA CLARA -- Defensive coordinator Vic Fangio has seen a mixed bag from 49ers cornerback Nmamdi Asomugha during the first week of training camp, he said Friday.
Asomugha is one of several players, including Tramaine Brock and Perrish Cox, who are in the mix to fill Chris Culliver's role as the 49ers' third cornerback. Culliver is out for the season with a torn ACL in his left knee.
Asomugha has put together two solid practices in a row, but Fangio said he needs to see more consistency from the 10-year veteran.
"We really didn't now what we were getting when we got Nnamdi," Fangio said. "He's had some good days out here and some days when we weren't sure if he'd be able to still have it. I think we're kind of in between on him right now.
"Hopefully, he'll still be able to have some gas left in his tank to go out there and play like he did prior to going to Philadelphia. So I think the jury is still out there."
Veteran cornerback Eric Wright remains an option. The 49ers acquired him in a trade with the Tampa Bay Buccaneers on July 19. Three days later, he failed the 49ers' physical and the trade was nullified. He is now a free agent after the Buccaneers released him, and general manager Trent Baalke said it's possible Wright could still play for the 49ers.

"I never met him," Fangio said. "They came in and told me we traded for him. And the next thing I knew they came in and told me he failed the physical. I never met him even though he was here for a day.
"I haven't met him and I haven't heard anything since."
