Offensive tackle Rashad Butler left the Pittsburgh Steelers for personal reasons on Monday after signing with the team during the weekend.
Butler and center Eric Olsen were added to the roster on Saturday to provide depth for the injury-plagued offensive line. Tackles Kelvin Beachum and Mike Adams and guard David DeCastro were hurt in Thursday night's loss to the Baltimore Ravens. Center Fernando Velasco is on injured reserve.
The 30-year-old Butler was released by the Cleveland Browns in early November. He has played in 50 career NFL games with the Browns and Houston Texans.
The Steelers play host to the Miami Dolphins on Sunday.
