Sri Lanka and New Zealand would be the first two nations to experience the effects of International Cricket Council’s (ICC) rule changes.The new ICC rules that were approved on Monday will come into effect when Sri Lanka host New Zealand in a Twenty20 International on Tuesday in Pallekele. The ICC has made several important changes to the playing conditions in all three forms of cricket, including amendments to Powerplays, Umpire Decision Review System (UDRS or DRS), no-balls and bouncers among others. The recommendations were made by the ICC’s cricket committee in June and endorsed by its chief executives committee later that month. An official statement from the ICC came late on Monday confirming the changes.Other important changes include amendment to the LBW (leg before wicket) protocols with the margin of uncertainty applicable to point of impact with the pad increased. Besides, henceforth the TV umpire would check for no-balls after every dismissal and advise the on-field umpires.In Test cricket, the participating countries can now decide whether to play a day-night Test match, with the competing boards deciding not only on the hours of play but also the specifics of the ball used. The teams can also change lunch and tea intervals to 30 minutes each with the ICC’s approval.In One Day Internationals (ODI), a maximum of two bouncers would be allowed per over, with blocks of Powerplays reduced from three to two.
