Packers rookie tight end Luke Musgrave has been placed on injured reserve due to a lacerated kidney sustained in last Sunday's game. It is unclear if he will be able to play again this season. Running back Emanuel Wilson has also been placed on injured reserve with a shoulder injury. The Packers have signed running back James Robinson and elevated fullback Henry Pearson and safety Benny Sapp III from the practice squad for the upcoming game against the Lions.
