Hadden (lower leg) was put on the active/PUP list by the Packers on Monday, Matt Schneidman of The Athletic reports.
The cornerback suffered a broken right tibia and fibula in a Week 17 clash with the Ravens last year, and he needed at least "a four- or five-month recovery" as of January, per Tom Silverstein of the Milwaukee Journal Sentinel. Hadden clearly still needs at least a little more time as training camp begins. If he's able to return during camp, he should be able to compete for a spot as a depth corner and special teamer.
