Arizona Cardinals running back Adrian Peterson was placed on injured reserve Thursday with a neck injury.
ESPN's Adam Schefter reported the news.
After signing with the Saints in the offseason, Peterson's tenure didn't go as planned. The 2012 NFL MVP had just 27 carries through the first four games before being traded to the Cardinals prior to Week 6.
The Cardinals were desperate for help at running back after David Johnson was injured in Week 1. Peterson had his two best games of the season after the deal, running for 134 yards in Week 6 against the Tampa Bay Buccaneers and 159 yards in Week 9 against the San Francisco 49ers.
