Aaron Wilson of Pro Football Network reported on Thursday that Osirus Mitchell, who was waived with an injury designation on Wednesday, was placed on the Green Bay Packers’ injured reserve on Thursday after clearing waivers. When a player is waived with an injury designation, another team can claim him to their 90-man offseason roster. The Packers waived Mitchell (and long snapper Steven Wirtel) yesterday as a corresponding roster move to adding running back Dexter Williams and safety Micah Abernathy before the squad’s Week 1 preseason opener against the San Francisco 49ers on Friday.
