The series was to start as Brisbane's Gabba ground on Thursday, but was deferred and the scheduled second test at Adelaide was brought forward as Cricket Australia and the Board of Control for Cricket in India shuffled the schedule to give players time to mourn.
Cricket Australia chief executive James Sutherland said it was "out of the question" that the players should be expected to play a test match a day after the funeral of a respected teammate and treasured friend.
Sutherland said CA would understand if, for some players, emotions were still too raw next Tuesday to face the challenge of test cricket and any player who felt unready for that match could withdraw without recrimination.
"Any player that is not comfortable or doesn't feel right, or there is medical advice to suggest they're not quite right, then we will obviously understand that," he said. "I'm sure the broader public will understand that as well," he said.
Veteran fast bowler Ryan Harris became the first player to publicly express misgivings about playing a test match so soon after the tragic death of a teammate, saying he hadn't yet decided whether he would take part.
Harris said Wednesday's service at Macksville " where the Australian sporting colors of green and gold and large banners and other tributes are adorning stores and public buildings around the town " would be an emotional trial for the Australian players and only after that could they address their thoughts to the test match.
"Let's get through that first. It's going to be pretty bloody hard," Harris told reporters in Brisbane. "It might be a bit of closure or it might take longer."
Harris said players would "probably like a little bit longer" to reconcile their emotions before facing a test preparation.
"But that is reality," he said. "There's a test series on and there are games to be played, that's what we have to prepare for."
In the week since Hughes' passing, Clarke has become a lightning rod for the emotions of his team and his nation. The 33-year-old Clarke may not have been a universally popular figure in the past and his relationship with Cricket Australia had been strained by his unorthodox efforts to prove his fitness for the first test after a hamstring injury. But all of those issues and impressions have been swept aside by the manner in which Clarke has conducted himself since the death of a teammate he described as "like a brother to me."
In articulately and unashamedly expressing his own grief, he made it possible for his teammates and compatriots to grieve. Clarke will draw from the same well of emotion when he addresses Wednesday's funeral service at the recreation hall of the Macksville High School, close to the banana plantation on which Hughes was raised. The Hughes family has invited the whole town to share a celebration of the 26-test veteran's life.
