Arizona Cardinals are on course for their fourth-straight victory as they lead the Indianapolis Colts by 24 points at half time in their clash at the University of Phoenix Stadium.
Carson Palmer threw for Larry Fitzgerald to complete a four-yard touchdown early in the game, but Adam Vinatieri shaved three points off the total before the start of the second quarter.
However, the same combination of Palmer and Fitzgerald stretched the Cardinals' lead to 14-3, before Jay Feely added three more with a kick from 48 yards.
A 22-yard return from Karlos Dansby put Bruce Arians's side further in front and Feely kicked from 50 yards to made it 27-3 at half time.
