The Fieldsman may stop the ball with any part of his person, but
if he wilfully stops it otherwise, 5 runs shall be added to the
run or runs already scored; if no run has been scored 5 penalty
runs shall be awarded. The run in progress shall count provided
that the Batsmen have crossed at the instant of the act. If the
ball has been struck, the penalty shall be added to the score of
the Striker, but otherwise to the score of byes, leg-byes, no
balls or wides as the case may be.
The number of on-side Fieldsmen behind the popping crease at the
instant of the Bowler's delivery shall not exceed two. In the
event of infringement by the fielding side the Umpire at the
Striker's end shall call and signal "no ball" at the instant of
delivery or as soon as possible thereafter.
Whilst the ball is in play and until the ball has made contact
with the bat or the Striker's person or has passed his bat, no
Fieldsman, other than the Bowler, may stand on or have any part
of his person extended over the pitch (measuring 22 yards/20.12
m. x 10 ft./3.05 m.). In the event of a Fieldsman contravening
this Law, the Umpire at the bowler's end shall call and signal
"no ball" at the instant of delivery or as soon as possible
thereafter. See Law 40.1.
