Ricky Ponting admitted Australia might field uncapped off-spiner Jason Krejza to bolster their slow bowling options.

The Australians head into the final match of the series 1-0 down and therefore needing to win in order to retain the Border-Gavaskar Trophy.

"The challenge that lies ahead is to take 20 wickets in Nagpur," Ponting said.

Australia's hopes in the series have so far been undermined by a lack of potency with the ball, especially from their slow bowlers.

The part-time options of Cameron White, Michael Clarke and Simon Katich have provided little discomfort for the home batsmen, highlighted by the fact they combined for just one wicket as India posted 617 for seven in the first innings of the drawn third Test in New Delhi.

Ponting admitted that if his side give up such an advantage in Nagpur their hopes of victory will be all but dashed, prompting him to suggest Krezja, the only specialist spinner in Australia's squad, could play when the final Test starts on Thursday.

Ponting added: "We probably need to look at Jason a little bit more closely. He was named as 12th man and he came very close to playing in this Test (in New Delhi).

"With a bit more work he will certainly come into consideration to play the next Test."

Should Krejza be called up to the squad he will be the third spinner to debut for the Australians in their past five Tests.

Whether Krejza will fare any better remains in doubt after he failed to impress in the tour opener against the Indian President Board's XI in Hyderabad. The 25-year-old did not take a wicket in the match and conceded 199 runs.
