Training camps will open across the NFL next week and Adrian Peterson is still unsigned.

Peterson hopes to play a 15th NFL season and the running back said last week that he still feels capable of contributing to a contender.

"The training is going well and I'm going to control the things that I can control right now, and, when that time comes, somebody will give me a call," Peterson told Aaron Wilson of Sports Talk 790. "That's all I'm asking for. My body feels good. I came out healthy from last season. My body feels strong. I still feel young. I still feel good. I'm ready to play ball."
