Arizona Cardinals have built a 15-point lead over the Atlanta Falcons after two quarters at the University of Phoenix Stadium.
The away team were first on the board, with Matt Bryant kicking over from 24 yards to secure an early lead.
That lasted until the second quarter, but then the Cardinals waged a full-scale assault with Carson Palmer on the front line.
He first threw to Larry Fitzgerald with almost the first play of the second quarter, before Andre Ellington rushed from 80 yards to score another touchdown.
In the mean time, Bryan had kicked another field goal, but the Cardinals now led by eight.
However, Palmer found Michael Floyd to touch down with just under two minutes left before half time.
