Buffalo Bills defensive end Ryan Denney took part in most of Wednesday's practice.
Denney might be able to return to action for the first time this year since breaking his foot in preseason.
"I hope to actually play this week; if not this week then soon," Denney said. "We thought I'd be ready to go after the bye; I wasn't quite there. The key factor is if it flares up overnight and doesn't recover before [today], that's not a good sign."
Denney had a screw inserted into the bone that runs along the outside of the foot. His return would be a big plus for the Bills, since he is one of the more effective No. 3 defensive ends in the league. He would give the Bills a strong four-man rotation at end, joining Anthony Hargrove as backups to starters Aaron Schobel and Chris Kelsay.
Cornerback Ashton Youboty (ankle) was limited in practice. Linebacker Leon Joe did not practice.
Quarterback Trent Edwards did not work. The Bills may not know until Sunday whether he can be No. 2 or No. 3 on the quarterback depth chart for the Bengals game. The right wrist Edwards sprained against the New York Jets still was swollen Wednesday. Edwards said he could not grip a football or shake hands.
"I'm doing better today but there's some pretty bad swelling in there, and it's limiting my motion and my strength in the right hand," Edwards said.
The Bengals are expected to be without Pro Bowl right tackle Willie Anderson. He has missed two of the last three games due to leg and foot injuries. Stacey Andrews, a fourth-year veteran, will likely make his sixth career start.
Running back Rudi Johnson, who has missed most of the last four games with a hamstring injury, returned to practice Wednesday for the first time since Sept. 19. He's expected to play. Kenny Watson has played well in Johnson's place, averaging 85.2 rushing yards a game. Watson suffered a mild concussion Sunday and sat out Wednesday's practice. The likelihood is Watson and Johnson, a formidable combination, will share rushing duties.
Dunlop has donated $5,000 to support Brian Moorman's PUNT Foundation, which provides assistance and family-centered programs to children with cancer. For every punt Moorman places inside the 20-yard line, Moorman asks fans to make a pledge to his Kicking for Kids program. Moorman has 13 kicks inside the 20 this year.
