On the first play of the half, Bills quarterback Kyle Orton threw an interception straight to Patriots linebacker Jamie Collins that led to New England’s only first-half touchdown.
Late in the half, Patriots defensive end Chandler Jones beat Bills left tackle Cordy Glenn to get to Kyle Orton, reach over his back for a strip sack and then recover the fumble himself, which put the Patriots at the Bills 24-yard line and led to a field goal.....
Finally, Bills running back C.J. Spiller fumbled with just six seconds left in the first half, which allowed the Patriots to complete one pass to the sideline and set up a 53-yard field goal for Stephen Gostkowski.
