Williams, Stewart questionable

CHARLOTTE, N.C. -- Carolina Panthers running backs DeAngelo Williams and Jonathan Stewart are questionable for Thursday's game against Miami with lingering injuries.

Williams skipped practice Wednesday with a sore left knee, but coach John Fox said they were "resting" him. Stewart practiced in full after sitting out Tuesday with a sore Achilles' tendon. Defensive tackle Damione Lewis is questionable with a sore shoulder, but practiced Wednesday. The biggest concern for Carolina is defensive end Charles Johnson, who is doubtful after missing his second straight practice with a strained pectoral muscle. Johnson plays mostly on passing downs. Fullback Brad Hoover and safety Charles Godfrey are also doubtful, but aren't expected to play because of ankle injuries.
