Maybe he was going to come in for a visit, and his agent called and said "don't bother seeing us unless you're offering Haynesworth money."
It happens. What is amazing to me about negotiations is how often the agent speaks on the client's "behalf." I have personally heard deals get killed because the agent wouldn't budge on a hard number, and he never talked to the client. Granted, this was an actor not an athlete, but still.
