NF play.

[DrMooreReferee]

Here's the play.

R makes a fair catch at his own 35. After that, A then throws a screenpass that gains all the way down to the 20 of B. On the tackle, B25 tackles A33 by the facemask. B is penalized half the distance to the 10 of B. A33 never leaves the field. However, he hangs out between the sideline and the 9 yard mark. After enforcement of the penalty, A then decides to free kick from B's 10 yardline. A33 still hasn't come back within the 9 yard marks and A/K kicks a successful FG through the uprights.

Is A/K penalized?

If so, what do you call it?

Interested to see what you guys think.
