Sydney - Cricket Australia's plan to stage two day-night Tests next season hit another hitch on Friday when the players' association sought a limit of one.
The initial schedule proposed the third Test between Australia and South Africa in November at Adelaide - the venue for the only previous pink-ball Test - and the series-opener against Pakistan in Brisbane in December be day-night matches.
South African players and officials have so far resisted the idea, although Pakistan has committed to playing its day-night match.
Australian Cricketers' Association chief executive Alistair Nicholson says "The feedback we are receiving from our playing group is that there still remain concerns over day-night Tests."
