Skipper Michael Clarke is determined to play in Australia's fourth Test against India despite a back injury and plans to train on Thursday in a final bid to prove his fitness.
Clarke batted down the order at No.6 in obvious pain and scored 18 on day five of the third Test in Mohali on Monday and has been unable to train so far this week.
"The team is training this afternoon so I'll head down with the team and try to do as much as I can," Clarke told reporters on the eve of Friday's dead-rubber clash in Delhi.
"At this stage, there is still doubt of me pulling up fit enough to play tomorrow but I've been given every opportunity.
"I'll have plenty of treatment again today.
"I've got another 24 hours to assess my fitness and do everything I can to get myself right to play this Test match."
Vice-captain Shane Watson, one of four players suspended from the third Test for failing to complete a homework assignment on time, is the likely skipper if Clarke is ruled unfit.
Clarke, 31, is Australia's leading run-scorer in the series and says he's determined to avoid missing a match through injury for the first time in his 92-Test career.
Watson, who has been battling with his form and question marks about his standards after being made ineligible for selection in the third Test because of a failure to complete a homework task, only returned to India earlier in the week after the birth of his first child.
India lead the four-match series three-nil.
