The Dallas Cowboys' acquisition of Trey Lance from the San Francisco 49ers does not have anything to do with the club's desire to extend Dak Prescott's contract.

"Didn't cross my mind, period, about an impact here regarding Dak," owner and general manager Jerry Jones said Saturday before the Cowboys' final preseason game against the Las Vegas Raiders. "I know that Dak wants to do anything we can do to improve this team and we're going to do it. The facts are that the decision to bring in as high a quality of talent as we could, that's involving young talent ... that's something that we've been trying to do, just never the opportunity seems to be there. So often we've been trying to do what we did today with this trade almost every draft since we've been drafting."
