Dallas Cowboys right guard Zack Martin has been ruled out for Sunday’s game against the Indianapolis Colts.
The perennial All-Pro has never missed a game since his rookie 2014 season, a string of 77 consecutive starts.
Rookie Connor Williams, who replaced Martin in the fourth quarter last week against the Eagles, will start at right guard at noon Sunday against the Colts.
Williams, who played left tackle at the University of Texas, started at left guard the first eight games. He injured a knee Nov. 5 against the Titans and missed two games after having surgery.
