Australia skipper Pat Cummins has been ruled out of the third Test against India as he returned home to attend his ill mother, hence paving way for Steve Smith to lead the side Indore.

Smith, who will captain the Australian Test team for the third time in little over a year, reckons that the promotion in role will help him bounce back in the ongoing Border-Gavaskar Trophy.

The stand-in Australia captain also recalled his dismissal to a sweep shot against R Ashwin in the second Test in Delhi, which left him "bedazzled and angry".

In India, Smith averages 52.21 with three centuries. However, he has managed to score only 71 runs in four innings so far in the ongoing series.

"I've played, what, 95 Test matches (94) and I don't think there's been too many times I've walked off the field and I've gone, ‘what the hell am I doing?’" Smith told reporters on the eve of the Indore Test. "I was pretty angry. There hasn't been too many times in my career where I've actually come off and just been bedazzled by what I've done. It wasn't my finest moment.

"Certainly something to learn from, I'm still learning as well. It wasn't the way I wanted to play, particularly when I had the field set for all of us – they had the field out.

"We probably just rushed things a little bit and it's something we'll talk about …when we've got them on the ropes, we can slow things down. We don't have to play at such a high tempo and risky tempo. Because we had them where we wanted them, we had men out and the ability to get off strike. We just rushed it."

Steve Smith is confident that the leadership role will help him regain his form.

"It normally brings the best out of me," he said of the captaincy. "I'm excited about leading this week in Pat's absence. I know these conditions well. It's kind of like my second home playing over here, I've played a lot in India, I understand the intricacies of the game and what the wickets are likely to do. I'm looking forward to it."
