Steelers sign another offensive lineman

PITTSBURGH -- The Pittsburgh Steelers’ offensive linemen get together every Thursday night to build camaraderie. They may need name tags this week, given what the latest wave of injuries has done.

The Steelers signed their third offensive lineman since Saturday when they agreed to terms with David Snow, who started two games at center last season for the Buffalo Bills. Snow, who was released by the Bills at the end of August, takes the place of offensive tackle Rashad Butler on the 53-man roster.

Butler left the Steelers for personal reasons before ever practicing with the team, and Pittsburgh used a roster exemption it was granted on Snow.

Snow and Eric Olsen, who signed with the Steelers on Saturday, are the newest members of an offensive line that has lost centers Maurkice Pouncey and Fernando Velasco to season-ending injuries.

Olsen is likely to dress Sunday against the Miami Dolphins and provide depth for the interior of the line.

Snow shuttled between the practice squad and 53-man roster last season in Buffalo after signing as an undrafted free agent. The University of Texas product played in five games for the Bills in 2012.
