(Reuters) - Arizona Cardinals coach Bruce Arians says he has "no idea" whether veteran running back Adrian Peterson will play again this season.


Peterson has missed the past two games with a neck injury and seems likely to miss Sunday’s match-up against the Washington Redskins.


The 32-year-old rusher was acquired by the Cardinals in a trade with New Orleans in October but has shown only flashes of the explosiveness that made him a seven-times Pro Bowler with the Minnesota Vikings.
