The Arizona Cardinals have certainly been one of the biggest surprises of the season - but it is not for good reasons.
The Cardinals are 1-3 and after being tipped for the Super Bowl this year, to say that they have been sub-par would be an understatement.
A divisional clash
It got worse for Arizona on Sunday as they not only lost at home to one of their divisional rivals, but they also lost their quarterback.

During the fourth quarter of their 17-13 loss to the LA Rams, quarterback Carson Palmer got hit and forced to leave the game.
He was then entered into the league's concussion protocol and with the Cardinals set for a quick turn around before their Thursday night game, his status has been questioned since Sunday.
With the team set to travel to San Francisco on Wednesday, head coach Bruce Arians has confirmed that Palmer remains in the concussion protocol.
Arians claimed during a conference call that there is still a chance that Palmer could play on Thursday night, but it currently doesn't look good.
Palmer has been at the Cardinals facility undergoing tests since Sunday but he remains in the protocol which likely means that he could be out for Thursday night.
Palmer being out would be very bad news for the Cardinals who have lost back to back games and are surely now desperate for a win.
If Palmer is unavailable for Thursday night, backup quarterback Drew Stanton will be brought in and he will need to do better than he did against the Rams.
Stanton threw two interceptions after entering the game against LA in the fourth quarter so he will drastically need to improve on that performance.
