Broncos released WR Javon Walker, according to ESPN's Michael Smith.
He's a big name, but Walker's contract and knee injury made it an easy choice by Denver. That no one chose to give up a late-round pick for Walker is telling. It's rumored that he could need microfracture surgery in the future, although he will have plenty of suitors lined up with MRI machines. Dallas, Washington, Philadelphia, and Tampa Bay have been rumored to be interested.
