Jennings, 31, spent seven seasons with the Packers before reportedly turning down an offer to re-sign with the team in favor of a more lucrative deal with the Vikings in 2013.
During his stint in Green Bay, Jennings notched at least 1,000 receiving yards in three seasons, earned three Pro Bowl nods and helped the Packers win Super Bowl XLV.
After he switched teams, Jennings made remarks critical of the Packers and star quarterback Aaron Rodgers. In a radio interview in August 2013, Jennings said he was "brainwashed" when he played in Green Bay.
"The way I left—if there was anything I would say I'm disappointed in, the way I kinda handled that. I don't want to say even kinda—I handled that situation," Jennings said on Tuesday. "Because I was—without coming out and saying it then—there was a sense of pridefulness to where it did hurt."
