The 2-2 Arizona Cardinals will travel east to face the 3-1 Philadelphia Eagles at Lincoln Financial Field this Sunday.
Arizona quarterback Carson Palmer realizes his offense could struggle to produce points on the road.
"It's a very, very good group," the 37-year-old said about the Philadelphia defense while speaking with reporters on Wednesday.
"They're playing at home. They're going to be keying the ball. And we've got to play our best to beat them."
The Cardinals are 1-1 away from the University of Phoenix Stadium this season.
