Basic spots for penalty enforcement
Fourth and 9 for K from its own 40 yard line. R10 holds K11 at K's 42-yard
line. R11 catches the kick at R's 25-yard line and is tackled at R's 29-yard
line.
-----------------------------
Ruling: If K accepts the penalty for holding, it will be K's ball, first and 10
from the 50-yard line. Post scrimmage kick enforcement applies only to R fouls
committed beyond the expanded neutral zone.(10.4.3E)Casebook
