Pakistan sent Shoaib Akhtar home from the Twenty20 world championships in South Africa on Friday after the fast bowler had a bust-up with teammate Mohammad Asif, officials said.
"The tour management has heard the two players and they have decided to send Shoaib Akhtar back. The Pakistan Cricket Board (PCB) fully endorses this decision," PCB chief executive officer Shafqat Naghmi told AFP.
"Shoaib Akhtar will be returning on the first available flight."
Nagmi added that the "decision was taken on complaints of discipline violation."
PCB sources said that the controversy-hit Akthar hit new ball partner Asif on the thigh with a bat after they had an altercation during a practice session in Johannesburg.
Pakistan open the Twenty20 World Cup with a match against Scotland at Durban on September 12 before facing arch-rivals India at the same venue two days later.
Akthar and Asif were caught up in a doping scandal less than a year ago.
