According to ESPN.com, the Cardinals have chose to place Peterson on injured reserve. "Obviously, I'm disappointed about going on IR when my body is still able to produce, but I look forward to returning completely healthy for another season in 2018". He ultimately rushed for 529 yards and two touchdowns, but he had not played since November 26, when he rushed for 79 yards against the Jaguars.
The 32-year-old has missed the Cardinals' last two games due to a neck injury, which left his status for Week 15 in question.

Perhaps the Giants could sway him if they landed Japanese two-way star Shohei Ohtani. Stanton is due to make $25 million in 2018.
"He'll heal fine", Cardinals coach Bruce Arians said. "I'm grateful for the opportunity that the Arizona Cardinals have given me to show I can still contribute on an National Football League team".
At 6-7 on the season, the Cardinals still have a very slim chance of making the playoffs in the NFC, needing to win all of their final three games and hope other results go their way. He also caught 11 passes for 70 yards. If Peterson is done with the Cardinals, there wouldn't be a huge market for him after he averaged 3.4 yards per carry this season and wasn't happy in New Orleans as a backup, which he would presumably be for any team that signed him in 2018.
Then, he fell back to earth, failing to rush for more than 79 yards over the next three games before suffering his neck injury.
