The Broncos and Javon Walker's agent, Kennard McGuire, are finalizing a five-year extension worth about $40 million that includes $15 million in option bonuses, $10 million due in 2007 and the other $5 million due in '08. Walker will play out the final year of his rookie contract this year plus receive a $1 million roster bonus from the Broncos. "We've got the parameters of an agreement," Shanahan said when the trade was made. "It's basically going to be in that six-year time frame. Obviously, there's no contract being signed but we we've talked and we're fairly close."
