Carson Palmer is likely out for the season with a broken left arm. Palmer will undergo surgery when Palmer returns to Arizona from London.

Bruce Arians expects Palmer to miss anywhere between eight weeks and the rest of the season.

Palmer left the game with Arizona down 6-0.

Palmer was replaced by Drew Stanton, who finished 5-of-14 for 62 yards and an interception. Palmer was 10-for-18 for 122 yards and an interception when he left the game.

Adrian Peterson is 32 and has rushed just 27 times for 81 yards this season but he wants to play for several more seasons.

"I have so much left," Peterson said. "I look to play at least four or five more years, god willing. I have a lot left in the tank. Stay tuned. You guys will be able to see that firsthand."

Peterson has heard discussions that he's no longer the type of running back that can carry an offense.

"Do I still got it?" Peterson responded to a question. "Well I don't think it's that mentality, 'do I still got it,' but that's all you hear from the media...'oh he lost it' this that and the other. So, of course, in my mind was like, OK, I know that's not the case. When I go out there I'm always putting my best foot forward and I feel like it will speak for itself."

The Arizona Cardinals have acquired Adrian Peterson for an undisclosed 2018 draft pick.

Peterson signed with the New Orleans Saints in the offseason but their backfield was crowded while the Cardinals are without David Johnson.

The Cardinals released Chris Johnson to create a roster spot for Peterson.

"We are always on the lookout for opportunities to improve our team and we look at this as one of those opportunities," general manager Steve Keim said in a statement. "What Adrian has accomplished in this league is well-established. Our need for a spark in our running game right now is also obvious and we are excited to give him the chance to provide that."
