Australia wait on Clarke

Shane Watson will have to wait another day before learning if he will captain Australia in the fourth and final Test against India in Delhi with skipper Michael Clarke to be given until the "last minute" to prove his fitness.

Clarke aggravated an ongoing back condition in the third Test, was forced to bat down the order in Australia's second innings and was noticeably in discomfort while running between the wickets.

If Clarke is ruled out, vice-captain Watson would almost certainly be handed the captaincy just 11 days after being suspended for a disciplinary breach and flying back to Australia to be by his pregnant wife's side.

But less than 24 hours before the Delhi Test starts, Clarke insists he has not yet ruled himself out.

"I've got a little bit of time left before I need to make that decision (on whether he will play or not)," Clarke said.

"That will be, I guess, guided by the expertise of Alex Kountouris our physio and our team doctor as well, Peter Brukner.

"My fingers are still crossed, I'm still hopeful, my back is still a little bit sore at this stage but I've got 24 hours before I need to worry too much about it.

"I'm fortunate that the selectors at this stage will give me to the last minute as well.

"(I will undergo) plenty of treatment today, get down to training and see how I go after training."

Clarke said Watson, James Pattinson, Mitchell Johnson and Usman Khawaja would be considered for selection after all received one-match suspensions for failing to deliver a presentation on team performance.
