The team placed him on injured reserve Wednesday, a week after he sustained another neck injury.
Tight end Justin Perillo was promoted from the practice squad to replace Richardson, and defensive back Kyle Sebetic was signed to the practice squad to replace Perillo.
Coach Mike McCarthy wouldn’t comment on Richardson’s future when asked about it on Monday. Last week, Richardson began feeling some discomfort in his neck after Wednesday’s practice. It was the same feeling he experienced in 2012, when a herniated disc required neck fusion surgery.
It’s rare for a player to come back from neck fusion surgery -- neither Nick Collins nor Jermichael Finley did – but Richardson was able to do so because his was lower in his neck (between the C-5 and C-6 vertebrae).
The Packers brought back Richardson this year as an restricted free agent when they matched the one-year, $2.55 million offer sheet he signed with the Oakland Raiders.
