With the Redskins defense still reeling from losing Brian Orakpo and Adam Carriker for the season, the unit received some encouraging news regarding two other starters on Friday.Cornerback Josh Wilson, knocked out of last weeks game with a mild concussion, is listed as probable for Sundays matchup against the Bengals. Wilson participated fully in practice on Friday after being limited on Wednesday and Thursday.If Wilson is able to suit up, he would likely play a significant role in attempting to shut down Andy Dalton and A.J. Green, Cincinnatis Pro Bowl quarterback-wide receiver tandem.Meantime, strong safety Brandon Meriweather, sidelined since the preseason with a sprained left knee, is listed as questionable for the Redskins home opener at FedEx Field. He was limited in practice all week.When Meriweather was injured in practice on Sept. 3, the originally diagnosis was that hed miss 2-4 weeks. So if he doesnt suit up against the Bengals, it would seem likely that hed play at Tampa Bay.
