Akhta has pleaded with the PCB to show leniency

The fast bowler hit Asif with a bat on the thigh, although he insists the blow was unintentional and he was provoked.

The Pakistan board has given a three-member committee two weeks to complete its hearing into the brawl.

Board member Shafqat Naghmi said: "We have issued a notice to Shoaib and asked him to appear before the committee on 6 October."

Akhtar escaped a fine of $5,000 last month for leaving a training camp in Karachi without informing the team management.

He appealed and the fine was suspended after it was accepted that he had told captain Shoaib Malik that he intended to leave.

Last year the fast bowler and Asif tested positive for a banned substance in out-of-competition tests conducted by the board and were sent home from the Champions Trophy in India.

They were at first banned and then cleared by a drugs inquiry tribunal and appeals panel of the board.

Akhtar has played just one Test and four one-dayers in the last 15-months because of fitness and disciplinary problems.
