An NFL source said the Packers and Broncos recently discussed the availability of disgruntled Green Bay wide receiver Javon Walker. There is a chance Walker will be traded by this weekend's draft, and the Broncos are one of several teams that have expressed interest in Walker, who is recovering from a torn ACL. The Packers are believed to be asking for multiple draft picks for Walker. Denver and other interested teams, including Philadelphia and San Francisco, are expected to talk with Green Bay as the draft approaches. There is a chance Denver will try to involve wide receiver Ashley Lelie in a deal. Lelie wants to be traded, and his agents and the team are shopping him. Denver is expected to draft a receiver early, perhaps with its first pick at No. 15, where Ohio State's Santonio Holmes and Florida's Chad Jackson could be available.
