CHENNAI, India, (Reuters) – Cricket’s governing body  will hold a two-day meeting in London to discuss the  possibility of playing day-night test matches and to find ways  of keeping the one-day format relevant amid Twenty20’s growing  popularity.

The International Cricket Council’s (ICC) cricket committee  will also look at the umpires referral system, which allows  players to call for television reviews, at the meeting at  Lord’s from today.

The referral system was first introduced nine months ago  and trialled in four test series.

“The committee will consider whether or not to recommend a  continuation of the system,” an ICC statement said on Saturday.

While day-night matches were introduced in one-day  international cricket three decades ago, test matches have  always been played in daylight.
