Multiple sources tell us that Packers quarterback Aaron Rodgers has parted ways with agent Mike Sullivan of Octagon.

He has yet to hire a new agent, as we understand the situation currently.

We’re assuming that Rodgers filed the appropriate paperwork to terminate the relationship before the Brett Favre saga was finally resolved.  Given the NFLPA’s five-day waiting period that prevents a new agent from signing Rodgers, there’s a chance that Rodgers might change his mind, now that Favre is out of Green Bay.

Then again, Rodgers still might be smarting about a rookie contract with so much money tied to actually playing.  Rodgers is making only $680,000 in 2008, but can trigger escalators that will bump up his pay in 2009, the final year of his contract.  He has lost millions by sitting behind Favre for three seasons.

It’s also possible that Rodgers directed Sullivan to get a new contract once Rodgers became the starter, and that Rodgers wasn’t happy with the progress.

Or maybe Rodgers noticed that Sullivan was one of the people chanting “Bring Brett Back” at practice on Tuesday.  (We’re kidding.)

If Rodgers doesn’t stay with Octagon, look for him to possibly consider David Dunn of Athletes First.  It’s also likely that Tom Condon of CAA will make a run at Rodgers.
