Adrian Peterson‘s season is over, but his career is not. The veteran running back says that he’ll be back on the field in 2018. “The good news is my neck injury doesn’t require surgery, but I’m told by Dr. Robert Watkins that the best thing for me is just more rest than the length of the season. 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,” Peterson said. “I’m grateful for the opportunity that the Arizona Cardinals have given me to show that I can still contribute on an NFL team.” Peterson averaged just 3.5 yards per carry for the Cardinals, but he did show flashes of his old self on a couple of occasions.
