FRISCO - Dallas Cowboys owner Jerry Jones said new backup quarterback Tony Romo has put the team first by accepting his role behind rookie starter Dak Prescott. But, Jones also believes Romo still has many good years left in him.

The Cowboys are giving Romo a chance to get some first-team snaps in practice, more so than the six that were given to Mark Sanchez every Friday of a game week, so that he's ready to go if called upon.

"It's not a goodbye," Jones said of Romo. "I think Tony has five years left of really competing for a Super Bowl. I believe Tony will be the quarterback on a Super Bowl team. I believe that strongly. We're talking generic now, and I have no plans for him not to be part of the Dallas Cowboys. Not a consideration."

Jones said he can see the Cowboys sticking with Romo over the next few years despite his contract and new backup role.

"It is very tenable for me to see on a long-term basis with us being strong at quarterback with these two," Jones said. "That's where we are."

Jones also said Prescott has earned the right to have a bad game or a bad few games without the rookie having to look over his shoulder and worry about Romo coming into the game.

And, as far as Romo getting more first-team snaps in practices now than Sanchez received earlier in the season ...

"There's a lot of difference between Tony Romo and Mark Sanchez, guys," Jones said, "that's speaking candidly."
