The Buffalo Bills will take the field at Gillette Stadium this afternoon without the services of two starters, as well as a third player that may as well be considered one. That player is defensive end Chris Kelsay, who will not play after missing practice Thursday and Friday with a neck injury.

Out, too, are defensive end Mark Anderson and cornerback Aaron Williams, who are both dealing with knee injuries. Replacing those two players in the starting lineup: Kyle Moore (who technically is replacing Kelsay as well) and Leodis McKelvin.

The Bills have four healthy scratches on the day: quarterback Tarvaris Jackson, offensive tackle Thomas Welch, linebacker Kirk Morrison and defensive back Mana Silva.

With those seven players out of the lineup, there are a couple of notable active players today. 2010 fourth-round wide receiver Marcus Easley will be active for the first time in his three-year career, though how much playing time he will get remains to be seen. Also active: cornerback Crezdon Butler, another third-year player that was signed from the Arizona Cardinals' practice squad just this week. He'll serve as the Bills' fifth corner against the New England Patriots.
