The St. Louis Rams (1-2) are set to visit a tough Arizona Cardinals (3-0) squad at the University of Phoenix stadium on Sunday for a 2015 NFL regular season Week 4 matchup.

Jeff Fisher's boys are coming off a disappointing 12-6 home loss to the Pittsburgh Steelers in a game marred by Ben Roethlisberger's knee injury caused by Rams safety Mark Barron's sliding sack, as per Yahoo Sports.

The defense was there for St. Louis, but they may have left their offense in the locker room as they were limited to two field goals and no touchdowns the whole game.

Nick Foles struggled the whole match, going 19-of-28 for 197 yards, and he would like to get better against the Cardinals on Sunday.

Meanwhile, Arizona's Carson Palmer-led offense continues to be menacing as they bullied the San Francisco 49ers, 47-7, in their Week 3 home game, via Fansided.

Palmer and running back Chris Johnson had two touchdowns each while defenders Tyrann Mathieu and Justin Bethel had scoring interceptions en route to the blowout victory.

It is expected that the Cardinals, particularly Palmer, will continue their momentum for a fourth straight win against the Rams.

Prediction: Cardinals win, 42-24.
