Carson Palmer's shoulder 'regressed,' QB seeks 2nd opinion and looks doubtful to play

Arizona Cardinals quarterback Carson Palmer continues to have issues with his right shoulder and his availability for Sunday's game in Denver against Peyton Manning and the Broncos is very much in doubt.

Head coach Bruce Arians addressed the media before practice on Wednesday and indicated Palmer's shoulder, which has had a nerve issue that has kept him from throwing a football, "regressed."

This comes after he had made progress and was able to start throwing before the bye last week.

Palmer was excused from practice Thursday to see a specialist for a second opinion about his shoulder.

There is a chance Palmer could play Sunday, but it seems like a longshot at best. Arians said Palmer would need at least "a day-and-a-half" of full strength throws to be considered fit to play.

It looks like Drew Stanton will get his third straight start, and perhaps it is time to worry about Palmer's chances for the rest of the season.
