FOXBOROUGH, Mass. -- Patriots running back Stevan Ridley missed Wednesday's practice due to a knee injury, the team announced via its practice participation report. It's unclear when the injury was sustained, though it likely occurred during the team's Week 4 win over the Falcons.

As expected, nose tackle Vince Wilfork (Achilles) and wide receiver Matthew Slater (wrist) were non-participants as well. Neither was spotted during the media availability portion of practice.

A total of 15 Patriots were limited during Wednesday's practice, including rookie receivers Aaron Dobson (neck) and Kenbrell Thompkins (shoulder), who both suffered the injuries during Sunday's game.

In addition, linebacker Dont'a Hightower (knee) and safety Tavon Wilson (hamstring) were among the new injuries listed on the report.

As has been the case over the past several weeks, tight end Rob Gronkowski (back/forearm) and wide receiver Danny Amendola (groin) were among the limited participants in practice.

For the Bengals, top cornerbacks Leon Hall (hamstring) and Dre Kirkpatrick (hamstring) did not practice. Both were inactive in Week 4.
