Because he tested positive, the protocols will prevent Martin from playing in Thursday night’s season opener against the Buccaneers.
Cowboys OL Connor McGovern will replace Martin in the starting lineup, per Machota.
Martin, 30, is a former first-round pick of the Cowboys back in 2014. He was in the final year of his four-year, $8.967 million contract when the Cowboys picked up his fifth-year option for the 2018 season.
Martin was set to make $9.341 million for the 2018 season when he agreed to a six-year, $84 million extension that included $40 million guaranteed.
In 2020, Martin appeared in 10 games for the Cowboys, making 10 starts for them at various positions.
