David Warner's future as a Test opener remains in doubt due to form and injury, with Australia's selection for the upcoming Ashes tour generating plenty of speculation.

Warner featured in Australia's first two Tests in India, but was subbed out of the match on day two of play in Delhi due to concussion. In Nagpur, Warner made a combined 11 runs across the two innings as the Australians slumped to a convincing loss.

With the Ashes tour set to begin in June, the Australians are yet to back Warner in for selection, with Australia selector Tony Dodemaide remaining tight-lipped, but refusing to confirm Warner would feature.

"We're worried about what we can get out of these remaining two Tests, obviously that's a clear focus for us at the moment," Dodemaide said on Wednesday.

"We'll address the Ashes planning (at a later time), but we are committed to picking the best fit and available players for Test series, particularly something as big as the Ashes.

"That's not a question that we've addressed so far.

"We are very keen, as everyone I'm sure at home would be, for us to get something out of this remaining series.

"We can still draw the series here, but it's a tough ask in order to do that, there's no doubt about that.

"Also for the World Test Championship, we're desperate to get a result out of these last two games."

Warner has flown back to Australia after being ruled out of the remaining two Tests due to injury, while Josh Hazlewood and Ashton Agar have also departed the Australian camp.

Mitchell Swepson will rejoin the squad prior to the third Test on March 1 after returning to Australia for the birth of his first child as the Australians try to show some improvement on a dire first two Tests.

"With Mitchell Swepson coming back as well that will essentially give us five spinners in the squad for the remaining two Tests, which is probably too many, really, saving an absolute disaster," Dodemaide said.

The third Test will begin on Wednesday, March 1 in Indore.
