Green Bay Packers wide receiver Randall Cobb is out for at least six weeks with a knee injury.
The team placed Cobb on injured reserve/designated for return on Tuesday. The designation requires a player to miss at least six games. Cobb was hurt during the 19-17 win Sunday over the Ravens.
The hobbled Packers also placed backup offensive lineman Greg Van Roten on injured reserve. He had a foot injury.
The team replenished its roster by signing tight end Jake Stoneburner and Myles White off the practice squad, and signed linebacker Victor Aiyewa to the practice squad.
Coach Mike McCarthy has already said linebacker Nick Perry (foot) is out for this weekend's game against the Browns, while receiver James Jones (leg) has a chance to play.
