Two inner circles shall be drawn on the field of play. The circles have as their centres the centre point of the popping crease at either end of the pitch. The field restriction area should be marked in 'dots'. The segment of the circles reserved for the slip positions shall not be demarcated. In the first 15 overs there must be a minimum of two stationary fieldsman within the 15 yard restriction of the striker at the instant of delivery.
Fractions are to be ignored in all calculations re the number of overs.
In the event of an infringement, the square leg umpire shall call and and signal 'No Ball'. In a delayed or interrupted match where the overs are reduced for both teams or for the team bowling second, no bowler may bowl more than one-fifth of the total overs allowed. Where the total overs is not divisible by 5, one additional over shall be allowed to the maximum number per bowler necessary to make up the balance. In the event of a bowler breaking down and being unable to complete an over, the remaining balls will be bowled by another bowler. Such part of an over will count as a full over only in so far as each bowler's limit is concerned.
