The Facts: The Arizona Cardinals are placing the Peterson on injured reserve. Peterson has missed the last two games with a neck injury.

Diehards Line: The Cardinals haven’t made a formal announcement of running back Adrian Peterson‘s move to injured reserve, but Peterson has confirmed that his season is over. Peterson gave a statement to Josina Anderson of ESPN after learning he will not be returning to action after going for further medical opinions on his injured neck. In addition to thanking the Cardinals for acquiring him from the Saints and giving him a chance to run as a lead back, Peterson also touched on his plans for the future. "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 said. As Profootballtalk.com notes, Peterson signed a two-year contract with the Saints, so the Cardinals can keep him around if they are so inclined. That may not be their choice as long as David Johnson is set to make a full recovery from the wrist injury that ended his season in the first week of the year, which would leave Peterson in a similar position to the one he was in after the Vikings released him in the offseason.
