The Facts: Palmer left Sunday's game against the Rams in the fourth quarter with a concussion.

Diehards Line:Palmer will enter the league’s concussion protocol and will have to be cleared before he is able to play. At this time, it is a wait and see game with Palmer. Fantasy owners should have a backup plan because the Cardinals are on a short week and play Thursday night. This may not be enough time for Palmer to get cleared. He did not return to the game and finished with 288 passing yards and a touchdown.
