Buffalo Bills wide receiver Marcus Easley missed the team's season-opening win against the Kansas City Chiefs with an illness that sprang up very suddenly, and now it appears that he'll miss at least one more game, but perhaps much longer.

Easley, a second-year player out of Connecticut that spent his entire rookie season on Injured Reserve with a knee ailment, played in the team's pre-season finale on September 1, but missed practices a week later leading up to the Chiefs game. Bills head coach Chan Gailey has already ruled Easley out of Week 2 action as of Monday afternoon due to this mystery illness.

What's more, the Bills may already be making contingency plans for being without Easley for much longer; the Facebook page for Ruvell Martin, for instance, indicates that the veteran receiver is headed back to Buffalo.

On the field, this development does not hurt Buffalo much, as the team appears set in receiver slot Nos. 1-4 for the time being. It certainly hurts Easley, however, who is missing out on practice reps and possible sub-package work due to this illness. Considering Martin's involvement, one wonders just how serious this is.
