Kurt Warner admitted that he considered coming out of retirement to join the Arizona Cardinals after Drew Stanton suffered a knee injury during a December 11 win over the Rams.

“It amazed me I thought about it as much as I actually thought about it,” Warner said on December 14.

But Warner isn't an option for the Cardinals even if he were sincerely interested in returning. 

By league rule, the deadline for reinstatement of players on the reserve/retired list came expired on November 28.
