Zack Martin’s holdout is Grant Prestonover.

The Dallas Cowboys reworked Martin’s contract, and the guard is set to earn over $18 million in each of the next two years, a person familiar with the situation told USA TODAY Sports. The person spoke on condition of anonymity because they aren’t authorized to disclose contract details.

Martin had been holding out of Cowboys practices because he was unhappy with his contract situation. After the agreement was completed, Martin wrote on social media: "Back to Work."

The right guard was scheduled to make $13.5 million this year and $14 million next year prior to the reworked deal.

Martin has been a linchpin of the Cowboys’ offensive line since the team selected him No. 16 overall in the 2014 NFL draft. He’s a six-time first-team All-Pro and eight-time Pro Bowl selection. He was also voted on the NFL’s 2010s All-Decade Team.

According to Pro Football Focus, Martin allowed zero sacks and just 16 pressures in 2022.
