Doucet, out with a concussion, was previously dealing with a rib injury and appeared on the injury report the last three weeks, but he played in Sunday's 58-0 loss to the Seattle Seahawks and caught two balls for seven yards. He has 28 catches for 207 yards on the year.
Williams was lost in the second quarter of the Seattle game with a hamstring injury. The loss of the third-year pro out of Tennessee hurt the Cardinals greatly, as fellow defensive tackle Darnell Dockett sat on the bench for much of the game. Talley's loss and the limited participation of star defensive end Calais Campbell makes the defensive line depth weak.
Also limited on Wednesday was defensive tackle Nick Eason (ankle), tight end Rob Housler (knee), safety Kerry Rhodes (abdomen), cornerback Greg Toler (hamstring) and receiver Andre Roberts (ankle).
Longsnapper Mike Leach was a full participant listed on the injury report, as was running back Beanie Wells, who only had six carries against the Seahawks for 18 yards.
