The Dallas Cowboys made Tony Romo the highest-paid player in franchise history after signing the quarterback to a six-year, $108 million deal contract extension, a league insider reported on Friday.

According to the sources, the Cowboys pulled off the deal in an effort to clear salary-cap space and keep their franchise quarterback for the remainder of his football career.

The blockbuster deal allowed the Cowboys to lower down the $18 million Romo was entitled to pocket this upcoming season and save $5 million in the process. Nevertheless, Romo will receive the highest guaranteed money ($50 million) in the NFL - $3 million more than Joe Flacco's six-year, $120.6 million deal.

Both parties did not engage in formal talks until March 4. However, Cowboys CEO and Romo's agent CAA's RJ Gonser already met several times even before the start of the free-agency period to negotiate about the lucrative extension.

"Tony has a special relationship with Jerry and Stephen and the entire Jones family," Gonser told ESPN on Friday. "He's a guy that's really laid down Dallas roots. He married a Dallas gal. He's a Dallas guy for life and he's a Cowboy for life as well. He feels extremely blessed."

Undrafted in 2003, Romo still made it to the Cowboys lineup and became the team's starting quarterback from thereon.

The 32-year-old Romo covered 25,737 passing yards on 64.7 passing percentage with 177 touchdowns and 91 interceptions.
