Tempe, AZ (Sports Network) - Arizona Cardinals quarterback John Skelton is listed as questionable for Thursday's matchup against the St. Louis Rams as he continues to recover from an ankle injury.
Skelton, who was carted off the field in the fourth quarter of Arizona's season-opening victory over Seattle, was a full participant in practice on Tuesday and Wednesday.
Backup quarterback Kevin Kolb took over for Skelton after the injury and has led the Cardinals to their first 4-0 start in 38 years.
Defensive tackle Darnell Dockett (hamstring) and linebackers Paris Lenon (knee) and Quentin Groves (hamstring) were all limited during Wednesday's session and are also listed as questionable.
Cornerback Michael Adams (hamstring), tight end Todd Heap (knee) and running back LaRod Stephens-Howling (hip) each missed practice on Monday, but returned on a limited basis on Tuesday and Wednesday and are listed as questionable as well.
Safeties Adrian Wilson (ankle/groin), Rashad Johnson (hamstring) and James Sanders (calf) and punter Dave Zastudil (right calf) were full participants in practice all week and are listed as probable.
