Pink balls have been used in Test cricket since 2015. Pink balls will be used to limit play lost to bad light in Test matches in a trial introduced by the International Cricket Council (ICC). The pink ball has been used in day-night Test matches since 2015, but has not before been interchangeable with the traditional red ball.

The ICC announced the introduction of the trial on Monday and BBC Sport has sought clarification on if the pink ball could be used during the first Test between England and New Zealand at Lord's beginning on Thursday. Both teams involved in a Test have to give prior agreement that a pink ball can be used in instances of bad light.

Halting play in Test cricket for poor light has become an increasing frustration for players, supporters and broadcasters in an age when most venues have floodlights. In 2024, more than half of the first day of England's third Test against Sri Lanka at The Oval was lost to bad light.

Speaking at the time, former England captain Michael Vaughan said: "You go to a pink ball and carry on. Teams will have to accept they get unlucky. All these ideas, you're not going to appease everyone. I just want to see them carry on."

The ICC has not specified the length of the trial, but the governing body has said it will work with the Marylebone Cricket Club (MCC) to research lighting technology for match officials and venues. There have been 25 day-night men's Tests since the first between Australia and New Zealand in Adelaide 11 years ago. Only one has taken place in England, when the home side beat West Indies at Edgbaston in 2017.

Day-night cricket has become a fixture in Australia, with the home side becoming an almost unbeatable force with the pink ball – Australia have won 14 of their 15 Tests under lights. There have been day-night Tests in every Ashes series in Australia since 2017-18, with the home side winning all four.

England are considering rejecting a day-night Test for their next Ashes tour in 2029-30, but the 150th anniversary Test between Australia and England in Melbourne next March will be a day-nighter.

The ICC board meeting in Ahmedabad also approved the allowance of head coaches to enter the field of play during drinks breaks in T20 internationals, mirroring a trend from franchise leagues. The governing body also "expressed concern regarding the growing expanse of franchise cricket".

The ICC said it would form a committee with the aim of harmonising the international and franchise calendars. In addition, Cricket Canada has had its ICC membership suspended with immediate effect over "serious breaches of its membership obligations".
