Practice report: Roddy White (knee) limited

FLOWERY BRANCH, Ga. -- Atlanta Falcons wide receiver Roddy White, who has battled injuries all season, showed up on Wednesday's injury report with a knee injury and was limited in practice.

It is unclear exactly when White suffered his latest setback, but he seems likely to play through the pain. White recently regained his form after battling a high-ankle sprain and hamstring strain for a good part of the year.

Two players were held out of Wednesday's practice: safety Thomas DeCoud and running back/special-teamer Antone Smith. DeCoud is going through stage one of the concussion protocol, although he has not been ruled out of Sunday's game against the Washington Redskins just yet. Coach Mike Smith said DeCoud still has to be cleared by an independent neurologist. DeCoud suffered the concussion attempting to tackle Green Bay Packers rookie running back Eddie Lacy.

Smith, who injured his knee playing special teams against the Packers, is day to day. He told ESPN.com his injury was related to his patella. It is not believed to be a serious injury. Smith observed Wednesday's practice without a helmet.

Four other Falcons were limited along with White: Tony Gonzalez (toe), Zeke Motta (hand), Sean Weatherspoon (shoulder), and Paul Worrilow (shoulder).
