The Atlanta Falcons placed guard Garrett Reynolds on injured reserve with a lingering back problem on Tuesday.
Reynolds had opened Atlanta's first six games at right guard before sitting out the team's last two contests due to the injury. He was replaced in the starting lineup by rookie Peter Konz.
A fifth-round choice of the Falcons in the 2009 draft, Reynolds made seven starts at right guard while appearing in all 16 games last season.
In a related move, Atlanta signed rookie guard Phillipkeith Manley to the active roster from the practice squad.
