Now that Adrian Peterson has arrived, it's fair to wonder about when -- and if -- David Johnson will be more than just a locker room-mate at running back. Johnson, on injured reserve with his surgically repaired left wrist, said rehab is "going great."

"Just got my cast, it's going good, wrist is feeling great," Johnson said. "We'll see how it goes."

Johnson wouldn't put a timetable on his comeback. "Wait and see how it heals," he said.

Coach Bruce Arians said on his SiriusXM NFL radio appearance Wednesday night that the "earliest" Johnson would return would be Thanksgiving. That weekend, the Cardinals host the Jaguars, and there would be six games left in the season. There are still five games in between then and now. Arians had previously put Johnson's return sometime between Thanksgiving and Christmas, so his comment this week remains in line with that.

Johnson said it was a "humbling moment" to see Peterson come in the locker room. "It's going to be cool to pick his brain and learn from it." (Johnson, however, was disappointed Chris Johnson was released, calling Johnson his mentor.)

"The opportunities I've had to talk to him were brief," Peterson said of his relationship with David Johnson. "He came to Minnesota, and I just had to congratulate him on the things that he had accomplished so far and things like that. He was just like, 'Hey man, I'm just trying to be like you. You're one of the guys that have paved the way.' So for me, I sit back and kind of just marvel and smile when I hear young guys like that say how I influenced them and their play and their work ethic."
