With no concrete developments in long-term contract negotiations, the Dallas Cowboys are likely to have to use their franchise tag on star quarterback Dak Prescott, according to ESPN's Adam Schefter.

The Cowboys and Prescott both want a long-term deal signed, but the tag appears inevitable at this point as the two sides disagree over the signal-caller's value, Schefter reports.

Prescott played the last year of his rookie deal in 2019. The 26-year-old completed 65.1% of his pass attempts for 4,902 yards and 30 touchdowns against 11 interceptions.

The two-time Pro Bowler has led the Cowboys to a 40-24 regular-season record and a 1-2 record over two playoff runs since Dallas drafted him in the fourth round of the 2016 NFL Draft.

Dallas has several offseason decisions to make regarding some of its most important stars. Wide receiver Amari Cooper and cornerback Byron Jones are both set to hit free agency once the 2020 league year officially begins on March 18.

Each team can use one franchise tag per offseason to retain a player's rights for one year. The tender offers a player a salary worth no less than the average of the top five salaries at the player's position for the current year or 120 percent of his previous salary, whichever is greater.

The franchise tender for quarterbacks was worth $24.86 million in 2019.
