All of the Redskins’ big free agent signings saw significant action in last Friday’s preseason opener except one — safety Oshiomogho Atogwe.

Atogwe has been bothered by a sore hamstring and hasn’t practiced with his teammates since Aug. 6. He missed Sunday’s practice, too. Redskins Coach Mike Shanahan said he wasn’t certain if Atogwe would be ready for Friday’s game at Indianapolis but seemed to think he’d return to the practice field soon.

“Really don’t know. Day by day,” Shanahan said Sunday. “I’ll let you guys know when he’s ready to go. I don’t think it will be too long.”

The Redskins have been without their starting defensive backfield, as LaRon Landry’s Achilles injury continues to heal. Atogwe and Landry have still been active during practices, mimicking safety movements during 11-on-11 drills deep in the defensive backfield. Atogwe is eager to return but knows he has to be patient.

“Hamstrings are tricky,” he said. “You never want to rush them, never want to come back too early because then it can be a nagging injury all season. We want to make sure we correct it now so come Sept. 11 and throughout, we’re ready to roll.”

“Once it feels right,” he continued, “when I can explode and extend, I’m going to be back out there with the fellas preparing for this season.”
