With an offensive line already beat up, the Falcons today signed fomer Bills lineman Terrance Pennington to the active roster.  This move was made after the team placed Renardo Foster on the injured reserve.  Foster was injured in Sunday’s loss to the Saints, as he tore his ACL in his left knee.  Pennington was a 7th round draft choice of the Bills back in 2006.  He started the last nine games of the 06 season at right tackle for Buffalo.  He was cut by the team before the 2007 season.  He is 6-foot-7 and weighs 325 pounds.  He played his college ball at the University of New Mexico.
