According to the Milwaukee Journal-Sentinel, the Packers might be interested in 49ers DT Ricky Jean Francois. Francois is an impending free-agent who served primarily as a backup last season.
The Packers are likely looking at him as a possible replacement for injured DT Jerel Worthy, who is expected to miss most of the 2013 season with a torn anterior cruciate ligament. Worthy had a solid 2012 season and his presence will be really missed if a replacement is not found soon.
The Packers are also rumored to be showing interest in former New York Giants DT Chris Canty. Despite this, Francois is still expected to be their top choice.
