As it turns out, Ego Ferguson's trip to Wisconsin lasted less than a week. The Green Bay Packers, who claimed the defensive lineman off waivers earlier this week, waived him following a failed physical, per the NFL's official transaction wire.
Ferguson's inability to pass a physical doesn't come as a total surprise. Knee trouble sidelined him for the majority of the 2015 season, and a shoulder injury cost him all of 2016. The exact reason for Ferguson's failed examination remains unclear, however.
Had Ferguson cleared medically, he would have competed for a reserve spot along the defensive line, most likely at the three-technique position or at nose tackle.
With Ferguson off the roster, the Packers now have just five full-time defensive linemen who have appeared in multiple regular-season games: Mike Daniels, Kenny Clark, Ricky Jean Francois, Christian Ringo, and Dean Lowry. The team could look for additional help on the free-agent market or in the upcoming NFL draft.
