It was contrary to a report by ESPN earlier on Wednesday that Witten offered to sign an injury waiver, releasing the Cowboys of any responsibility in case he was injured in the game because of the lacerated spleen he suffered in the preseason.
Witten said the decision to play was a medical one, plain and simple, as did Jones.
"I want to be clear. Never one time, any time did anybody in the club or me talk to Jason about a waiver," Jones said. "The decision was clear-cut. It was a good crisp, good decision by experts ... fine, fine doctors. It was a real diagnosis that he would play. It was real clear."
Coach Jason Garrett said Witten was cleared to play be team doctors Tuesday night.
"It was a medical decision all along," Garrett said. "This was not an emotional decision by me as a coach in any way, shape or form. I was clear with Jason from minute one when this happened, I said it was completely out of my hands. It was not going to be a football decision. It was going to be a medical decision between Jason and the doctor. He was cleared to play."
