The Packers have placed cornerback Quinten Rollins on injured reserve (Twitter link via Adam Schefter of ESPN.com). Rollins was carted off the field on Sunday after suffering an ankle injury. 
By placing Rollins on IR, the Packers will buy themselves some time on what to do with Aaron Rodgers. After breaking his collarbone, the Packers will almost certainly have to park Rodgers on IR. Doing that will officially rule him out for two months, however, so the Packers want to exhaust every other option before making that irreversible decision.
Rollins, 25, had 17 total tackles through six games this year. He made only one start in 2017, but he made ten starts for Green Bay in 2016.
Rollins’ roster spot will be filled by the promotion of quarterback Joe Callahan.
