Green Bay Packers wide receiver Javon Walker has been conducting personal business on his own pretty much since the start of the regular season, but according to a source close to the NFL Players Association he has officially parted ways with agent Drew Rosenhaus. In order to terminate their business agreement, Walker has to file papers with the union declaring his intentions, which he apparently did. Other agents interested in recruiting Walker are not allowed to speak to him about contractual matters as long as he has an agreement with a specific agent, but according to the source Walker is officially no longer associated with Rosenhaus. Walker was unavailable for comment and Rosenhaus did not return a phone message seeking comment. Packers general manager Ted Thompson was out of town and also unavailable for comment. Rosenhaus signed Walker less than a year ago and led him through a tumultuous off-season in which the Packers receiver boycotted off-season workouts and threatened to hold out from training camp in the hopes of forcing the team to renegotiate his contract. The Packers did not budge and Walker reported to training camp under the terms of the deal he signed as a rookie in 2002. He has one year left on that contract after this season.
