Adelaide's annual Test match will be an all-day affair for the first time since 2014 after Cricket Australia (CA) conceded that the BCCI would not accept a pink-ball fixture.
CA's chief executive James Sutherland had held out hope of a day-night match until as recently as last week's announcement of the schedule for 2017-18, but his arguments failed to convince the BCCI.
BCCI acting secretary Amitabh Choudhury wrote to Sutherland on Monday, saying the Committee of Administrators, the supervising authority of the Indian board, had decided that India would only be ready to play pink-ball Test cricket sometime next year. "I am directed to say by the Committee of Administrators that India would begin to play in the format only in about a year's time," Choudhury wrote in an e-mail, accessed by PTI. "Under the circumstances, I regret to say that the proposed day-night Test cannot be played and all Tests will have to have the conventional structure."
