All-Pro offensive guard Zack Martin has agreed to a six-year, $84 million contract extension that includes $40 million in guaranteed money, according to a report from ESPN’s Adam Schefter.

The deal will make Martin, 27, the highest-paid offensive guard and among the NFL's highest paid offensive linemen.

After skipping the Cowboys’ organized team activities earlier this off-season, Martin showed up for this week’s mandatory minicamp with reports that an extension was close.

Martin was selected by the Cowboys 16th overall in 2014 and has since been named to the Pro Bowl in all four seasons and has been named a first-team All-Pro twice and a second-team All-Pro twice.
