Australia paceman Shaun Tait has been ruled out of September's Twenty20 World Championship because of injury.
The 24-year-old fast bowler had hoped to be fit in time after undergoing an operation on his right elbow in June.
But he has been unable to train with the Twenty20 squad because of an infection in the problem area.
And chairman of selectors Andrew Hilditch has been forced to admit defeat, with the world championship starting on September 11.
"The news is very disappointing for Shaun after such a successful World Cup campaign and I know he was looking forward to being part of the first ICC World Twenty20," Hilditch said.
"We're really keen, fitness permitting, for Shaun to take part in the India tour in October though.
"It's a very important one-day series and a tremendous springboard for our domestic season of international cricket."
Tasmania fast bowler Ben Hilfenhaus is the beneficiary, although his experience of the shorter form of the game is limited.
He took two wickets and proved Australia's most economical performer in the 77-run victory over England in January though, and Hilditch is convinced he will bring real quality to the group.
"The flip side is that this presents a great opportunity for a good young fast bowler who had such a good season last year," Hilditch added.
"Ben is highly regarded, and the chance to be part of an Australian touring squad will greatly assist his development."
Australia open the tournament against Zimbabwe on September 12 and then face England two days later, before the Super Eights stage begins.
