Match Playing Conditions
24. No Ball
Law 24 shall apply subject to the following:
24.1 Law 24.1 (b) Mode of delivery
Law 24.1 (b) shall be replaced by the following:
The bowler may not deliver the ball underarm. If a bowler bowls a ball underarm the umpire shall call and signal no ball, and the ball is to be re-bowled overarm.
24.2 Free Hit after a foot-fault no ball
In addition to the above, the delivery following a no ball called for a foot fault (Law 24.5) shall be a free hit for whichever batsman is facing it. If the delivery for the free hit is not a legitimate delivery (any kind of no ball or a wide ball), then the next delivery will become a free hit for whichever batsman is facing it.
For any free hit, the striker can be dismissed only under the circumstances that apply for a no ball, even if the delivery for the free hit is called wide ball.
Field changes are not permitted for free hit deliveries unless there is a change of striker (the provisions of clause 41.2 shall apply).
The umpires will signal a free hit by (after the normal No Ball signal) extending one arm straight upwards and moving it in a circular motion.
24.3 Law 24.6 Ball bouncing more than twice or rolling along the ground
Law 24.6 shall be replaced by the following:
The umpire shall call and signal No ball if a ball which he considers to have been delivered,
without having previously touched bat or person of the striker, either (i) bounces more than once or (ii) rolls along the ground before it reaches the popping crease.
