Butler missed Monday's media night due to the effects of the flu. On Thursday, the Boston Globe reported Butler was "still feeling the effects of a nasty illness."
Eric Rowe started for Butler alongside Stephen Gilmore. Rowe, who has started 10 of 17 regular-season games in two seasons for the Patriots and is a former Eagle, was beaten by Alshon Jeffrey for a 34-yard touchdown in the first quarter.
Three years ago, Butler was the fifth cornerback on New England's depth chart coming into Super Bowl XLIX but replaced Kyle Arrington a nickel defensive back in the third quarter. Two plays after allowing a juggling 33-yard reception to Jermaine Kearse, Butler intercepted Russell Wilson's pass to Ricardo Lockette at the goal line with 20 seconds left to preserve New England's 28-24 win and fourth Super Bowl title.
The Patriots signed him to a first-round tender worth $3.91 million last spring. This season, Butler finished with 60 tackles and two interceptions while starting 15 of 16 games.
