The two sides talked throughout the offseason and made little progress, and Jennings doesn't want negotiations to be a distraction. He wants to concentrate on his on-field production and helping the Packers to reach the postseason.
But with a contract that expires after the season, he also now looks to be one of the top free agents, if not the top free agent, in the Class of 2013.
"I'm not worried about whether I'm going to end up here or whether I'm getting a contract done," Jennings said last week. "That will take care of itself. Right now, my (mind) is on the 49ers, and it will be on the next opponent and the next opponent after that. If I'm here, I would love to be here. If I'm not, it is what it is.
"At the end of the day I'm going to play football, I'm going to play 100 percent every single snap. This is my locker, I want this to be my locker until I hang my cleats up and decide I'll give this locker up to someone else."
Jennings is one of several high-profile players the Packers' front office will have to address in the foreseeable future. Contracts for outside linebacker Clay Matthews and defensive lineman B.J. Raji run out after the 2013 season, and Aaron Rodgers is vastly outperforming a deal that runs through the end of the 2014 season.
