The event technical committee of the Twenty20 World Cup has approved Ryan Harris as replacement for injured Brett Lee in the Australian squad for the tournament, which begins in the Caribbean on Friday.
The confirmation was conveyed to Cricket Australia, which has sought a replacement for Lee for the entire event.
Lee suffered a muscle strain on his right elbow during Australia's loss in the warm up game against Zimbabwe on Tuesday.
30-year-old Harris from New South Wales has played two Tests, 12 ODIs and two Twenty20 Internationals.
Any injury-based replacement requires a written submission to the event technical committee along with a diagnosis from a medical practitioner as to the extent of the injury. Once replaced, a player cannot return to the squad.
The eligibility of a replacement player is subject to approval by the ICC before he can be officially added to the squad.
The event technical committee of the Twenty20 World Cup consists of David Richardson (ICC, chairman), Robert Bryan (Tournament Director), Campbell Jamieson (IDI representative), Tony Howard (WICB representative), Alan Wilkins (independent nomination) and Sanjay Manjrekar (independent nomination).
Australia open their campaign against defending champions Pakistan here on May 2 and then take on Bangladesh in Barbados on May 5.
