PITTSBURGH -- The Pittsburgh Steelers have lost another offensive tackle before he played a game for them.
Rashad Butler has left the team for personal reasons, two days after the Steelers signed him to provide depth for their battered offensive line.
Butler is still listed on the 53-man roster, but it appears as if he is gone before even practicing with the Steelers.
The Steelers lost offensive tackle Levi Brown this season before he played in a game. Brown suffered a triceps injury while warming up for a game against the Jets, and the Steelers placed the seventh-year veteran on injured reserve.
The Steelers signed center Eric Olsen and Butler last Saturday after placing center Fernando Velasco on injured reserve because of an Achilles injury. Depth at tackle might still be an issue with Kelvin Beachum and Mike Adams dealing with knee and ankle injuries, respectively.
The Steelers returned to work today, practicing in preparation for their Sunday game against the visiting Dolphins.
