As long as the Cowboys keep winning, rookie Dak Prescott will remain the team's starting quarterback.

Despite saying he didn't want to speculate, Jerry Jones made that clear during his Tuesday morning radio interview.

"You want to be very mindful of what you got going, which right now we got a lot of chemistry going," the Cowboys owner and GM said on 105.3 The Fan's Shan and RJ show [KRLD-FM]. "That has got to be really recognized if you're making a decision."

Jones, who after Sunday night's win over the Eagles announced that Prescott would start this Sunday at Cleveland, provided no update on when Romo will return.

Romo returned to practice last week in a limited role, throwing in some individual drills and in scout team work. Head coach Jason Garrett said Romo would do more of the same this week.

"I know that Tony is making a lot of progress," Jones said. "I do think that unquestionably he's going to be ready to go at some point near the end of the year. We'll be able to evaluate things at that time."

Jones said once Romo returns, he does not believe the Cowboys need to announce who is their starting quarterback.

"He's a veteran," Jones said. "He wants this team to have all the success it possibly can have. Dak feels the same way. Coaching staff, they don't need to know. We'll just play it out.

"Tony has no issue with doing what's best for the team. Absolutely no issue with doing what's best for the team."
