The correct answer is: an indirect kick from the spot of the foul, because obstruction is always an indirect kick. (The only time a PK is awarded is if the foul would have resulted in a direct kick.) If the ball was inside the goalie box, the defending team may build a wall that is less than 10 yards away; otherwise the wall is the usual 10 yards.

Whistle blows. . .what is the call?
