DCL NO BALL Rules that do not match with ICC rules

DCL Rule
A bouncer over the shoulder and a ball that sails above the waist, bowled at a batsman in an
Upright position standing at his crease is considered a NO BALL

There is no warning for bouncer in DCL

ICC Rule
One bouncer above the shoulder is allowed and its umpire's duty to warn the bowler.

DCL Rule
The ball following the front-foot no-ball is deemed a ‘free hit’ ball. The fielding team can position
their fielders in any manner. The batter and the non-striker can be out only by way of a run-out. If the free hit ball is a wide or a no-ball, the following ball will be a free hit ball as well. This goes on until a legal delivery is bowled.

ICC Rule
The free hit in ODIs applies to all foot fault no balls and not just front foot no balls.
Fielding positions cannot be changed if the same batsman faces the free hit ball who faced the NO ball... but if the batsmen had taken a run in the NO ball and now the other batsman is facing the free hit ball fielding captain is allowed to make fielding changes
