Williams' agent has been given permission to gauge trade interest in his client, NFL.com reports. Williams was a healthy scratch from Sunday's game following totals of eight catches, 142 yards and one touchdown through the first five games this season. However, given Williams' unhappiness with his role as the Bills' No. 3 receiver, his agent has requested a trade elsewhere. Although Buffalo is not actively shopping Williams, the team will reportedly do its due diligence by listening to any potential interest the wideout garners.
