A free kick is touched by Team A prior to going 10 yards; Team B has the option of taking the ball at the spot of the illegal touching.
6-1-3-b
b. Any other touching by Team A is illegal touching, a violation that, when the ball becomes dead, gives the receiving team the privilege of taking the ball at the spot of the violation.
An invalid fair catch signal is given, and the ball is caught at the B7. Ball comes out to the B25.
6-5-3-a (exception)
ARTICLE 3. a. A catch after an invalid signal is not a fair catch, and the ball is dead where caught or recovered. (Exception: During a free kick, if a Team B receiver gives any waving signal that does not meet all of the requirements of a valid fair catch signal, and subsequently catches the ball behind the B-25 yard line the ball belongs to Team B at its own 25-yard line).
My question is, are there any more violations, that are not fouls, besides these two?
