Help me, help me, help me. I fully agree with SJ's initial response. But, and this is a big BUT for me. Rule 10-4-4-a says the basic spot is the spot of the foul for illegal batting or illegal kicking. Of course, there is no mention as to where the actual enforcement spot is.
And I still can't find an actual rule statement that tells me where to enforce a loose-ball foul beyond the line (or in this case beyond the spot of the free kick). Lots of info about running plays but nothing I can find re loose-ball plays. WTF !
