TEMPE, Ariz. -- Carson Palmer was going through the NFLs concussion protocol on Monday and Arizona coach Bruce Arians said he wasnt ruling out the quarterback for Thursday nights game at San Francisco.The loss of Palmer would be another blow to an Arizona team that has stumbled to a 1/3 start after opening the season with the highest of expectations.Palmers head slammed to the turf on a sack by Aaron Donald late in the Cardinals 17-13 home loss to the Los Angeles Rams on Sunday.He got better last night and improved, Arians said. I talked to him last night, and his wife. Like I said, its all up to the doctors.Asked if he was encouraged, Arians said, Yeah. From what I thought yesterday, I thought there was no chance.Palmer was doing some physical activity as part of the protocol on Monday and would not have to practice in order to play against the 49ers, Arians said.He doesnt practice on Wednesdays anyway, the coach said. Its not like theyre doing something he hasnt seen before. Hed be more than ready to go.Arians said a decision on whether Palmer will play probably wont be made until probably about the time we get on the plane Wednesday.If Palmer cant go, the job falls to Drew Stanton, who re-signed this offseason to return as the Cardinals backup.Before Sunday, Stanton hadnt had significant playing time since Palmer went down with a torn ACL in the 2014 season. Stanton went 5-3 as a starter then. In nine games played, he threw for 1,710 yards and seven touchdowns with five interceptions before he too was lost for the rest of the season with a knee injury.The Cardinals still had a chance when Stanton took over for Palmer on Sunday, but he threw an interception with 1:34 to play. Stanton got Arizona to the Rams 37 in the final seconds, but his desperation pass was intercepted as the game ended.Stanton has been with Arians since the coachs days at Indianapolis and the two came to Arizona together. I think that is why Im here, to fulfill these kinds of opportunities if it presents itself, Stanton said. That all remains to be seen, and again, last game is behind now and unfortunately I didnt do what I was hoping to do and really what I thought I was going to do. Now its time to move on and prepare for San Francisco and try to win a division game.Arians said the game plan would not change with Stanton.Not one bit, Arians said. Theyre so similar and we dont have to change anything when hes in there.The Cardinals are trying to figure out just whats gone so wrong. Some of the problems are turnovers. Some is communication, especially in the revamped secondary.Were just not playing our best football, Tyrann Mathieu said. Defensively, were not creating enough turnovers. Critical situations in the game we cant get off the field on third downs. I think thats what it really comes down to. Plays we made in the past, were just not making those plays right now.Mathieu is embracing the situation, though.Backs against the wall, were 1-3, he said. Everybody that believed in us, they dont believe in us no more so its just us now. We prefer that.Mathieu, playing only free safety and kept out of his usual do-everything role while he recovers from knee surgery, said Monday that its time to get back to his old job, where he often plays in the box and is a disruptive force all over the field.Were 1/3 man, he said. Its not really time for me to sit back and play it slow. I feel great. I look forward to wherever coach puts me at. But if I have anything to say about it, Ill be back in my normal spot. ... Im ready to cut it loose.Arians has said he was waiting for Mathieu to come to him to tell him he was ready to resume that Honey Badger role. Has Mathieu done that?Thats what I just did, he said with a big smile.Game notes Running back Chris Johnson is out with a groin injury so Andre Ellington will move to the backup spot behind David Johnson. ... Safety Tyvon Branch (groin), tight end Darren Fells (shoulder), defensive tackle Ed Stinson (toe) and defensive lineman Josh Mauro (chest) also did not participate in Mondays practice.---AP NFL website: www.pro32.ap.org and AP NFL Twitter feed: http://twitter.com/AP-NFLCheap Air Jordan Australia For Sale .
