Zack Martin's new deal with the Dallas Cowboys is expected to be record-breaking.
The Cowboys are expected to sign the All-Pro guard to a six-year extension that will make him the highest-paid player at his position with the most guaranteed money, NFL Network's Ian Rapoport reports.
Andrew Norwell preivously signed the richest deal of any guard in free agency when the Jacksonville Jaguars inked him to a five-year, $66.5-million deal, 45.11 percent of which was guaranteed, according to Spotrac.
Martin, a four-year pro, is generally regarded as one of the best - if not the best - players at his position.
He has just one year left on his rookie deal, which would pay him $9.3 million for the 2018 season.
