Cardinals list QB Skelton, DT Dockett as questionable for Thursday night game against Rams

Arizona Cardinals quarterback John Skelton is listed as questionable for Thursday night's game at St. Louis even though he fully participated in the team's last two practices.

Skelton sprained his right ankle in the season opener against Seattle. Kevin Kolb relieved him and has led the Cardinals to their first 4-0 start in 38 years.

In all, nine Arizona players were listed as questionable, including defensive tackle Darnell Dockett (hamstring), running back LaRod Stephens-Howling and tight end Todd Heap (knee). All three missed Sunday's 24-21 overtime victory over Miami.

Also questionable for Thursday are two other starters — inside linebacker Paris Lenon (knee) and defensive tackle Dan Williams (foot).

All of those listed as questionable, except Skelton, were limited in Wednesday's practice.
