Chiefs quarterback Damon Huard was moved to the injured reserve Wednesday and will not play again this season.
Huard suffered an injury to his right thumb in the first half of Sunday's 34-10 loss to Tennessee.
Brodie Croyle also was moved to the IR.
Tyler Thigpen will start Sunday at the Jets, and Ingle Martin will be the backup. Newly signed quarterback Quinn Gray will be the third passer.
