The Bills made a pair of moves on their eight-man practice squad Tuesday adding a defensive back and an offensive lineman.
Buffalo signed DB Mana Silva and G/OT Andrew Jackson to the practice squad.
Silva (6'1" 214), who has appeared in five games for the Dallas Cowboys the past two seasons, was on Buffalo's practice squad last season for a span of five weeks (Weeks 10-14). He was most recently cut from the Cowboys 53-man roster when the team signed punter Brian Moorman last week.
Jackson (6'5" 300) is a guard-tackle prospect that was a former seventh-round pick of Atlanta (2011). The Fresno State product spent the 2011 season on the Falcons practice squad, but was released by the club during final cuts this past summer.
To make room for Jackson and Silva on the practice squad the Bills waived CB Isaiah Green and TE LaMark Brown.
