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. Source: Sports Network
