Joe Root has played in all seven of England's previous pink-ball Tests
Joe Root has questioned whether the Ashes needs to include a pink-ball Test as England prepare to meet Australia in a day-nighter in Brisbane.
England are 1-0 behind in the five-match series after defeat in Perth and will attempt to level the series from Thursday at the Gabba - a ground where they have not won since 1986.
Day-night Tests were sanctioned by the International Cricket Council in 2015 in the hope audiences would be "encouraged and improved".
The concept has been embraced in Australia. Thirteen of the 24 day-night Tests to have been played have been in this country.
