Johnson worked out for the Packers on Tuesday, Rob Demovsky of ESPN.com reports.
The Packers lost Kylin Hill (knee) for the season, and they are expected to be without Aaron Jones (knee) for a week or two, leaving AJ Dillon and Patrick Taylor as the only healthy running backs on their active roster. Johnson was waived by Detroit in May and has since spent time with the Eagles and 49ers. The 2018 second-round pick has only appeared in one game this season, playing exclusively on special teams.
