Wide receiver Greg Jennings is a popular player in the NFC North.
A source told FOXSports.com that the Vikings and the Packers have expressed interest in signing Jennings now that he is an unrestricted free agent.
Jennings, 29, is considered the top wide receiver remaining on the market after Miami signed Pittsburgh's Mike Wallace at the start of Tuesday's signing period.
Minnesota, which had interest in Wallace, has the salary cap room to make a run at Jennings. The Vikings also desperately need to upgrade their wide receiver corps after trading Percy Harvin to Seattle.
The Packers would still like to re-sign Jennings even though he wasn't named their franchise player at a cost of $10.54 million against the team's salary cap. Jennings led the league with 30 catches of 40-plus yards between 2007 and 2011. Jennings, though, only played in eight games last season because of a sports hernia. The Packers also have depth at the position led by Jordy Nelson, Randall Cobb and James Jones.
Jennings, 29, tallied 425 receptions for 6,537 yards and 53 touchdowns the past seven seasons in Green Bay.
