His contract with the Green Bay Packers expires after the season, and he has missed eight games because of injury. He has three regular-season games left to show his stuff to the Packers and 31 other NFL teams that might be interested in the wide receiver's services.
Jennings said he doesn't know of any contract talks between the Packers and his agent.
"I don't know, I've seen guys who have been hurt all year come off injuries and get paid," Jennings said. "I'm not concerned about it. It's the nature of the game. Has it dipped into my pocket some? Probably. But my resume speaks for itself. What I'm able to do is not going to change."
The two-time Pro Bowl receiver has seen this recently happen in Green Bay. Center Scott Wells, defensive tackle Cullen Jenkins, guard Daryn Colledge and running back Ryan Grant all left in free agency without much negotiation with the team.
"That means something," Jennings said. "I don't think we're dumb. I don't think we're naive, I don't think those guys were naive, either. Going into it, that was my way of thinking. I saw the trend. I don't feel like I'm any exception. I go about my business as if I'm no exception."
The Packers are a draft-and-develop program that would rather part ways with a player one or two years too early than too late. Second-year pro Randall Cobb has flourished with Jennings out, and the Packers' coaching staff loves his Percy Harvin-type ability. Wide receivers Cobb, Jordy Nelson and James Jones all are under contract.
"Do I think it's more likely that I will (play for another team)?" Jennings said. "I can't answer that with a definitive yes or no. Am I preparing myself for possibly having to play somewhere else? Absolutely. Is that what I would want to do? Not at all. They know that."
Jennings will be one of the highest-ranked players in free agency if the Packers let him hit the market. Since Jennings is 29 years old, this could be his last major contract.
