The cricket world will have new set of rules and conditions that are set to be introduced today. The significant changes include restriction on dimensions of the bat, the introduction of player send-offs for misconduct and changes to the Decision Review System.

The umpires can now send the players off during a match for serious misconduct, with the new powers vested in them. The thickness of bats has been restricted and umpires will be given a “new bat gauge” to check their legality.

The player send-off will be applied to Level 4 offences while the Level 1 to 3 offences will continue to be dealt with under the ICC Code of Conduct.

Also the Level 4 offences mainly comprise of threatening to assault and making inappropriate and deliberate physical contact with an umpire. Physically assaulting a player or any other person and committing any other act or violence also constitute of Level 4 offences.

Another important change with respect to run outs is that if a batsman is running or diving towards the crease with forward momentum, and has grounded his/her bats behind the popping crease but subsequently has lost contact with the ground at the time of the wickets being put down, the batsman will not be run out. The same theory will also apply for a batsman trying to regain his/her ground to avoid being stumped.

For boundary catches, airborne fielders making their first contact with the ball will need to have taken off from within the boundary, otherwise a boundary will be scored. Also, a batsman can now be out caught, stumped or run out even if the ball bounces off the helmet worn by a fielder or wicket-keeper.

The mentioned changes will be applicable across all formats, as will be a change in the DRS rules by which a review will now not be lost in case of a decision that remains unchanged, which solely depends on the result of an “umpire’s call”.
