The Green Bay Packers added some depth to the end of their roster before Sunday's game against Minnesota by activating defensive end Jerel Worthy and safety Sean Richardson from the physically unable to perform list on Saturday. To make room, the Packers put cornerbacks Casey Hayward (hamstring) and James Nixon (knee) to season-ending injured reserve. Source: Scout.com SteveRobWhatever's Take: Worthy is returning from a torn ACL he suffered late last year. Meanwhile, all-rookie CB Casey Hayward's second season didn't amount to much. He finished with six INT's last year but this year he's been stuck battling a hamstring injury that finally's gotten the best of him.
