Dak Prescott is set to sign a record-breaking, $240million contract with the Dallas Cowboys, according to reports.

Prescott's future has been up in the air but, just hours out from their season opener against the Cleveland Browns on Sunday, it appears the Cowboys have struck a deal with their quarterback.

The deal includes a guaranteed $231m and an $80m signing bonus.

With an annual salary of $60m, Prescott will become the highest-paid quarterback in NFL history.

This is the second extension the 31-year-old has penned with Dallas, where he will remain through the 2028 season.

Prescott led the NFL for completions (410) and touchdowns (36) last season.
