The Packers have claimed Micah Pellerin off waivers from the Colts. The rookie safety had signed with the Colts as an undrafted free agent out of Hampton University last month. Green Bay waived receiver Marcus Rivers from the University at Buffalo. The Packers have a starting safety spot to fill after they released Nick Collins earlier this offseason. Second-year pro M.D. Jennings has been working with the starters so far during OTAs.
