Tempe, AZ - Arizona Cardinals quarterbacks Carson Palmer and Drew Stanton are both questionable for Sunday's game against the Washington Redskins.

Palmer has been dealing with a shoulder injury that occurred in Arizona's season-opening win over the Chargers, while Stanton suffered a concussion during last Sunday's loss at Denver.

Both were limited participants in practice all week.

If neither can go, rookie Logan Thomas will make his first career start. Thomas was 1-of-8 passing against the Broncos, with his only completion an 81-yard touchdown to Andre Ellington.

Guard Paul Fanaika (ankle/calf) is also listed as questionable.
