The Green Bay Packers placed defensive lineman Johnny Jolly on injured reserve with a bulging disk in his neck and tight end Brandon Bostick with a foot injury.
No one has replaced them on the active roster yet.
The Packers didn't activate wide receiver Randall Cobb from injured reserve-designated to return.
Jolly may need surgery to address a C-5 vertebra issue.
Bostick had season-ending foot surgery this week.
