Right tackle Bryan Bulaga was placed on injured reserve by the Green Bay Packers with a hip injury suffered in the team's Week 9 victory over the Arizona Cardinals.
Bulaga met with a specialist over the team's bye last week and the team made the decision Monday to place him on IR.
After Bulaga left the Cardinals game, left guard T.J. Lang moved to right tackle, with Evan Dietrich-Smith taking Lang's spot.
The Packers also signed linebacker Vic So'oto on Monday. He played in seven games for Green Bay in 2011 and appeared in four games for the Oakland Raiders this season.
