In 1986 he signed with the Green Bay Packers as a free agent, and became the opening day starter at right offensive tackle. He sat out all of the 1988 season with a career-threatening hip injury. His return and consistent play kept heralded rookie Tony Mandarich on the bench in 1989. In 1991, after four seasons as a starter for the Packers, he signed in Plan B free agency with the Dallas Cowboys, where as a backup at tackle and guard, he helped Emmitt Smith win the NFL rushing title in 1991 and 1992. He also helped the Cowboys reach Super Bowl XXVII, although he was one of two players declared inactive for Super Bowl Sunday (the other was Robert Williams).
