Australian leg spinner Shane Warne will reportedly call in his psychologist to explain how the leg spinner's weight problems led to him taking a diuretic.

Sydney's The Daily Telegraph on Monday said the psychologist would be part of a team of experts hired by Warne for his Australian Cricket Board hearing.

Warne is still awaiting the result of his B sample after the A sample from a test performed in Sydney last month tested positive for a diuretic.

Warne is expected to learn the B sample result on Monday.

He has been charged with using a prohibited substance and faces a two year ban from all cricket.

Meanwhile, International Cricket Council (ICC) general manager Dave Richardson revealed Australia could bring a new player into the squad even though Warne's likely omission would be due to suspension, not injury.

"That's the rule set out before the tournament," said Richardson.

"If they bring someone in they can't bring Warne back. They haven't told us what they are intending to do as yet. I guess they are still waiting for (Warne's) B sample results."

There had been conjecture about whether Australia should be permitted to replace Warne because he was being forced out by his decision - innocently or otherwise - to take the diuretic.

It was a different situation to the plainly unlucky injury that ended South African Jonty Rhodes' tournament.
