The Green Bay Packers have placed offensive lineman Jason Spitz on injured reserve with a lower-back injury.

Spitz, who plays center and guard, appeared in five games this season. He is part of an offensive line that has allowed a league-worst 31 sacks.

The Packers also signed wide receiver Biren Ealy from the practice squad on Saturday. The 6-foot-2 Ealy appeared in four games with Tennessee in 2007 and spent the 2008 season on the Titans' practice squad.
