Players may now be sent off for "serious misconduct" as part of a number of new playing conditions unveiled by the International Cricket Council (ICC).

It follows rule changes announced by the Marylebone Cricket Club (MCC) earlier this year.

The alterations also include a restriction on the dimensions of the bat and changes to the decision review system (DRS) and will be effective in all series starting September 28 or later.

In a new playing condition pertaining to players' conduct, a player can now be sent off the field for the rest of the match for "serious misconduct".

Threatening to assault an umpire, making inappropriate and deliberate physical contact with an umpire, physically assaulting a player or any other person and committing any other act of violence all constitute level four offences which will see a player removed from the match.

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

There will also be no more top-up reviews after 80 overs of an innings, meaning that there can only be two unsuccessful reviews in each innings, while the DRS will now also be allowed to be used in Twenty20 Internationals.

"Most of the changes to the ICC playing conditions are being made as a result of changes to the laws of cricket that have been announced by the MCC," said ICC general manager Geoff Allardice.

"We have just completed a workshop with the umpires to ensure they understand all of the changes and we are now ready to introduce the new playing conditions to international matches."

Changes now also restrict the size of the edges of the bats as well as their thickness.

The restriction on the length and width of bats remains unchanged but the thickness of the edges cannot be more than 40 millimetres and the overall depth can be 67mm at the most.

Umpires will be issued with a new bat gauge, which they can use to check a bat's legality.

As per the new run-out rule, a player would be considered to have made his or her ground even if the bat bounces after being grounded behind the crease by a running or diving batter.

This would mean that once a batter has landed the bat behind the crease, he/she will not be ruled run-out or stumped.

The same interpretation will also apply for a batsman trying to regain his or her ground to avoid being stumped.

In the field, airborne players need to start from within the boundary before coming into contact with the ball, failing which a boundary would be awarded.

Also, a batsman can be given out caught, stumped or run-out even if the ball bounces off the helmet worn by a fielder or a wicket-keeper.
