It's official: Dak Prescott is the Dallas Cowboys' QB

FRISCO, Tex. -- You may ask yourself what else can Dak Prescott do?

He has led the Dallas Cowboys to a franchise record eight straight wins and to the best record in the NFL. He led the Cowboys to two touchdowns in the final two minutes to take down Ben Roethlisberger and the Pittsburgh Steelers 35-30 before the largest crowd ever at Heinz Field.

He has now officially supplanted Tony Romo as the starting quarterback. After missing the first eight games of the season with a fractured bone in his back, Romo is now healthy and ready to do.

He will serve as a backup to Prescott when the Cowboys play the Baltimore Ravens next Sunday.

"We are going to let the decision make itself," owner Jerry Jones said. "Dak has got a hot hand and we are going to go with it. ...It's just going with the obvious. You are going with how the team is doing right now. It must not be obvious because I get asked about it every time I open my mouth.

"It's not hard. It's not hard at all. Tony would make the same decision. That's what you do."

Prescott says he will continue to operate with business as usual and go about his preparation the same as has done over first nine games of the season.

"As I always said, it doesn't affect how I go about my business, how I game plan or prepare during the week," Prescott said. "I'm just thankful to have the opportunity ... I'm just coming in each and every day trying to give my team a chance to win no matter what my role is."

His role is as starting quarterback of the Cowboys.

Jones said Romo is on board with the decision.

"Let me be real clear on that," Jones said. "There is no equivocation. He is totally committed to doing the very best thing to win the game. It's just going with the obvious. You are going with how the team is doing right now. It's not hard. It's not hard at all. Tony would make the same decision. That's what you do."

After not dressing for a game since last Thanksgiving, Romo finally is ready to return though it likely wasn't in the role he envisioned. He declined comment after the game.

"He's ready," Jones said. "He had a great week. He practiced all three days. He hadn't done that in about 18 months, two years. He practiced all three days and didn't have any lingering negative things from that and really was able to use every aspect of his leverage of everything he needs to make his throws. He didn't have any lingering effects from it. That's great news for us and certainly look forward to having him on the roster."

While Jones said Romo will be the backup against the Ravens, head coach Jason Garrett said a final determination has yet to be made. He said Romo had a good week of practice last week and he is hopeful that he can be the backup Sunday.

"We're certainly hopeful that would happen based on what he did last week, but again we'll take his situation day by day and hopefully he'll have a good day on Wednesday," Garrett said of Romo being active against the Ravens.

Tight end Jason Witten said Romo is excited to get back into the action, but his main focus is on helping the team win, even in a backup role.

"It'll be good to have Tony out there," Witten said. "I mean his spirits are high. He's certainly focused on doing whatever he can in any capacity to help this football team win games. And I know that he's going to approach it that way and know what he's all about. It'll be good to get him out there."
