IRVING, Texas -

The Dallas Cowboys and Tony Romo have reached an agreement on a blockbuster deal that makes him the highest-paid player in franchise history, ESPN reported Friday afternoon.

The contract is a 6-year extension worth $108 million, with $55 million guaranteed, ESPN reported.

The guaranteed money is $3 million more than what Joe Flacco recently received from the Baltimore Ravens.

This is the fourth contract Romo has signed with the Cowboys since joining the organization in 2003.

By inking a new deal with Romo now, the Cowboys will lower his salary-cap number and free up money to sign other players.
