That Fair Catch Kick attempt in the Giants-Ari game

I didn’t know what to make of it, so I didn’t really mention the free kick attempt by Arizona in the Giants-Arizona game. So I did a little research…
At the end of the first half, after the Giants punted with a few seconds to go in the half, Arizona called for a fair catch.
After a fair catch, an NFL team has the right to take a free kick from the line of scrimmage on the next play. If the kick goes through the uprights, the kicking team scores 3 points. It is also known as a “free kick field goal.”
Basically, the difference between a free kick and a field goal is that it has to be after a fair catch, there is no snap, the defense has to be 10 yards back of the attempt, and the kicker cannot use a tee.
The Cardinals missed the attempt.
