As is the case with nearly every NFL team, the Dallas Cowboys are in the midst of their effort to prepare their books for the start of the upcoming league year. The latest step in that process was restructuring the contract of guard Zack Martin, according to NFL Media.

The move will save the Cowboys $13 million. Martin originally had a base salary of $18 million, thanks to the reworked two-year deal he signed with Dallas last offseason, and along with the prorated $10.5 million signing bonus from his previous deal, he was set to count against the cap for $28.5 million. Now, he’ll count for approximately $15.9 million, according to Over the Cap, with the remainder of the base salary conversion spread out over three void years that were attached to the contract last summer plus an additional void year added in this conversion.

Martin has been in the NFL for 10 seasons and has made both the Pro Bowl and one of the two All-Pro teams nine times, with the lone exception being the 2020 season, when he played only 10 games. He’s been a first-teamer seven times, including each of the last three years. Widely considered one of the best guards and overall offensive linemen in the NFL for the entirety of his time in the league, Martin is heading into the final year of his contract and will turn 34 years old during the 2024 season.

Coupled with reports that the Cowboys might not re-sign stalwart left tackle and likely future Hall of Famer Tyron Smith, it sure seems like significant changes could be coming to Dallas fairly soon. Even Martin’s restructure could point in that direction, with 2024 being the last year on his deal and only void years remaining after this.
