Tony Romo is making history in the “Big D”…

The 32-year-old Mexican American NFL quarterback has agreed to a deal with the Dallas Cowboys, a blockbuster six-year extension worth a whopping $108 million, making him the highest paid player in franchise history.

In the first year of the extension, Romo will make $26.5 million, and after two years, he will make $40 million. Romo’s money over the first three years — with the likelihood that Dallas keeps him the next three seasons — will be $57 million.

Romo now has a seven-year deal worth $119.5 million, of which $11.5 million was included as part of a $25 million signing bonus spread over the course of the deal. The $11.5 million is what Romo was set to make in 2013 before the extension.

“In today’s game, every NFL franchise understands the importance of production and continuity at the quarterback position, and, historically, few franchises have enjoyed those benefits more than the Dallas Cowboys,” Cowboys owner and general manager Jerry Jones said in a statement. “We are very confident in this investment and commitment.”

Romo’s salary-cap number was $16.8 million in the final year of his current deal, but he now will count $11.8 million against it, saving the Cowboys $5 million. His average salary for six more years will be $18 million. For 2013, Romo receives a base salary of $1.5 million.

As part of the deal, Romo will receive $55 million guaranteed from the Cowboys.

“I am excited about the year ahead and some of the changes that we have made to allow us to be a better team going forward,” Romo said in a statement. “This is an organization that always gives us a chance to win, and that is always the main focus here. We haven’t had the type of success that we have all wanted the last few years, but I do know that we are on the verge of doing that.”

The Cowboys had hoped to sign Romo to an extension last summer, but the quarterback put the contract talks on hold so he could concentrate on the season.

Negotiations heated up this week, when the Cowboys submitted their first proposal before Romo’s side countered with its own. Negotiations continued at a feverish pace once a framework for the deal was established and middle ground was eventually reached.

This is the fourth contract Romo has signed with the Cowboys since joining the organization in 2003. He signed a six-year, $67 million deal in 2007.

Romo is the Cowboys’ all-time leader with 174 touchdown passes and holds the franchise’s single-season records for passing yards and touchdowns.
