Riddled by injuries for much of the season, the Packers’ offense is starting to get healthy down the stretch. Two days after quarterback Aaron Rodgers returned to the starting lineup, the Packers activated wide receiver Randall Cobb from injured reserve, the club announced this afternoon. The 23-year-old Cobb is one of the Packers’ top playmakers. He hauled in 29 passes for 378 yards and two TDs in five games (four starts) before suffering a broken leg in Green Bay’s Oct. 13 victory at Baltimore.
