Tony Romo will soon be an even richer man.

The Cowboys plan to sign Romo to a contract extension this month that could keep him in Dallas the rest of his career.

Romo, who turns 33 in April, has one season left on his contract. He’s set to count a team-high $16.8 million against the team’s salary cap in 2013, but the Cowboys can cut that number in half by signing him to a long-term extension.

Owner Jerry Jones said he would like to see Romo retire as a Cowboy.

“That means we’ve had some success,” Jones said.

The Cowboys signed Kyle Orton to a three-year contract a year ago in free agency to back up Romo.

While the team believes it’s set at quarterback for the foreseeable future with Romo and Orton, developing someone who could eventually replace Romo will take on more urgency in coming years.

“You would like to have a young guy to try to bring along, certainly,” quarterbacks coach Wade Wilson said.

But the only talk around Valley Ranch these days involving a quarterback is getting an extension done with Romo. The Cowboys don’t plan to seek another quarterback in free agency.

Instead, they would like to upgrade their offensive line to give Romo more time to dissect defenses and improve a running game that finished next-to-last in the NFL last season.

In short, the Cowboys plan to build around Romo, not replace him.

Bottom line: The Cowboys don’t have much money to spend in free agency and certainly won’t be adding a quarterback with so many other areas they need to address.

Romo will probably retire as a Cowboys player, and Orton gives the Cowboys one of the league’s top backups.
