Cricket is all set to go the football way of using yellow card to prevent players from abusing umpires and also sledging. This will first be introduced in county and club level tournaments in London. If ECB sees its working then they may include it in first class matches. ECB have taken permission from MCC which manages the law of the game overseas. Yellow card may mean that a player is sent off the fiels for some overs say 12. Introduction will help to bring dicipline in games as its more required in club level matches.
The umpires need to be given more power. If this works then one may see it introduced too in international matches. If this law is introduced then only one team that will have to chage their playing style....are the Australians!!!!!!
