Ashes Test matches are unlikely to be played with a pink ball in the near future, according to the head of the Australian Cricketers' Association.
South Africa this week overcame their reservations to agree to play a day-night Test against Australia in Adelaide in November, before Pakistan experience the new concept in Brisbane in December.
In January, Cricket Australia chief James Sutherland said the next Ashes series could feature a day-night Test, but ACA chief Alistair Nicholson says CA must work to get the format right after last year's inaugural day-night Test between Australia and New Zealand finished inside three days, with players from both teams unhappy with the pink ball's movement, durability and visibility under floodlights.
Their reservations were backed up by on Wednesday by Alastair Cook, who said he was opposed to day-night Tests being introduced in Ashes series.
"A lot of the games have really good attendances, so I don't think that's a series where you need to do it at this precise moment in time," he said.
And Nicholson said: "The concerns of the players run deep, and with Alastair Cook's comments we see they also run internationally.
"The message from players all over the world is clear: 'We want the best quality test cricket. To achieve this there is a lot of work to be done on the pink ball format.'"
Nicholson also wants next year's home Ashes series against England to stay with the traditional red ball, given the reservations expressed by rival captains Steve Smith and Cook.
"As the issue stands the collective position on Ashes cricket is that it should be preserved as a red ball contest, and the two Test captains are clearly expressing this view," he said.
"With 140 years of high quality Test cricket between Australia and England we want to ensure that contest remains at the highest standard ... the players and the fans expect this.
"Again the test is to get this format right first, before any consideration can be given to expansion."
