ATLANTA — The Atlanta Falcons have placed center Peter Konz on injured reserve with a left knee injury, dealing their battered offensive line another devastating blow.
Konz is Atlanta's fourth starting offensive lineman to suffer a season-ending injury.
Konz replaced Joe Hawley after Hawley and right tackle Lamar Holmes suffered season-ending injuries in a loss at Minnesota on Sept. 28. Left tackle Sam Baker was lost for the year in a preseason game.
Konz hurt his knee in the Falcons' 29-7 loss at Baltimore on Sunday.
Atlanta signed offensive tackle Jonathan Scott to the 53-man active roster on Monday.
Konz, a second-round pick from Wisconsin in 2012, has made 27 starts at center and right guard.
Scott has 35 career starts with the Lions, Bills, Steelers, and Bears in eight seasons.
