The Arizona Cardinals are on course to move further clear at the top of the NFC West as they lead the Pittsburgh Steelers 10-3 at the break.

The Cardinals took the first drive and it looked promising after Carson Palmer found John Brown deep for a 45-yard pickup, but they stalled just outside the redzone and a personal foul penalty forced them to punt.

However, Arizona would find the endzone on their very next drive with Palmer lofting it to Michael Floyd for a three-yard touchdown, the wide receiver's first TD of the season.

The Steelers pulled three points back thanks to a field goal, but backup quarterback Michael Vick was pulled from the game with a minor injury for the final few snaps of the drive.

Arizona regained their seven-point lead just before the half as Chandler Catanzaro put up another three points as both teams headed into the locker room.
