"I'm feeling good," he said. "It's a matter of going through this week. I'm feeling very hopeful."
If Doughty is healthy, the Redskins would return both starting safeties as Brandon Meriweather's one-game suspension has ended. Rookie Bacarri Rambo played well at Denver, so it's possible he could still see increased action.
Doughty practiced in a limited fashion two days last week but could not practice Friday as symptoms returned. He couldn't make the flight to Denver, where the Colorado native's family and friends would be attending.
That made it tough for Doughty, but he said he's also glad he was honest about the symptoms.
"As a player you have to be honest and that's what I was," Doughty said. "I really tried to get ready and wanted to be ready and tried to convince myself I was ready and at the end of the day I wasn't ready. I'm disappointed I missed the game, but from a medical standpoint I don't have any regrets."
