In a sign the Bills are at least doing some due diligence on interior offensive linemen, offensive guard Tyronne Green and center / guard Doug Legursky visited the club on Tuesday, reported.

Legursky, who turns 27 on Sunday, has appeared in 50 games for Pittsburgh in the last four seasons, starting 17 contests. He has been the primary backup to center Maurkice Pouncey the last three seasons, but the 6-foot-1, 315-pound Legursky has also seen some time at guard.

The Bills already have three former Steelers interior linemen in the fold, including starting right guard Kraig Urbik. The club also has former Pittsburgh draft picks Chris Scott and Keith Williams on the roster. Bills G.M. Doug Whaley was the Steelers’ pro scouting coordinator before joining Buffalo three years ago.

The 6-foot-2, 316-pound Green started 13 games at left guard for San Diego in 2012. He had a brief stint with New England this offseason but was let go on Friday.
