Australian fast bowler Shaun Tait was on Monday ruled out of next month's ICC Twenty20 World Cup with an elbow injury, Cricket Australia said.
It said it was seeking approval for Tait to be replaced by Tasmania fast bowler Ben Hilfenhaus.
Chairperson of selectors Andrew Hilditch said he was advised that Tait's elbow has not recovered sufficiently from recent surgery for him to take part in the tournament in South Africa from September 11-24.
"This 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.
"The flip side is that this presents a great opportunity for a good young fast bowler who had such a good season last year.
"Ben Hilfenhaus is highly regarded, and the chance to be part of an Australian touring squad will greatly assist his development.
"We're really keen, fitness permitting, for Shaun to take part in the India tour (in October) which is a very important one-day series and a tremendous springboard for our domestic season of international cricket."
Australian team physiotherapist Alex Kountouris said Tait has recovered slower than expected from right elbow surgery.
