Cricketers could be sent off or banished to a sin-bin for 10 overs this summer as lawmakers try to address increasing levels of bad behaviour.
The MCC is to launch a trial that will, in effect, bring red or yellow cards to club, university and schools cricket to stamp out excessive sledging and curb the increase of violent behaviour.
Five matches in England were abandoned last year due to violence and, after consulting umpire associations around the world, the MCC has decided action needs to be taken to support officials by introducing a code of conduct with four levels of offences.
Proposals include sending off a player for the rest of the match for the most serious level-four offences, such as threatening an umpire, assaulting a player, official or spectator, and racist abuse. If it is a batsman, he will be "retired out".
For a level-three offence, such as threatening and intimidating behaviour, or bowling a deliberate beamer, suggested sanctions include 10 overs in the sin-bin.
