The Cardinals thought their starting quarterback was nearing a return last week, when Carson Palmer chucked balls 30 and 40 yards down the field preceding the bye weekend.
After a frustrating few days, his reappearance is not imminent.
Palmer missed practice on Wednesday to see another specialist for a shoulder injury which has regressed, coach Bruce Arians said. Palmer hopes to find a treatment which can effectively awaken the nerve problem which has kept him sidelined since the season opener against the Chargers on Sept. 8.
“He threw a bunch last Thursday and Friday and then regressed, so we’re hoping we can find out why,” Arians said.
“It was afterwards (when) something swelled back around that nerve, and it went back to sleep,” Arians added.
Drew Stanton is likely to draw his third start for the Cardinals. He has been serviceable, but Palmer's absence is a downgrade for Larry Fitzgerald and Michael Floyd.
