Herschelle Gibbs has been dropped by South Africa for the forthcoming one-day series against Bangladesh after breaking a team curfew.

South Africa beat Bangladesh in the tour-opening Twenty20 yesterday evening, in which Gibbs contributed 18 from 10 balls. But he will now play no part of the three ODIs and the selectors have chosen not to replace him. It is likely Justin Ontong will open the batting with Hashim Amla in Gibbs' absence.

"Herschelle's behaviour is unacceptable in the context of team discipline," said the South Africa coach, Mickey Arthur. No details were given of the offence, but this is not the first time Gibbs has been in hot water. Mohammed Moosajee, the team manager, said that Gibbs would be required to attend an alcohol rehabilitation course.

"We are not trying to punish Herschelle but rather to help him," Moosajee said. "He has been under a lot of pressure lately, notably from the publicity surrounding his recent divorce. It is clear that he has developed a problem that needs to be addressed.

"Herschelle can rely on the full support of Cricket South Africa to get his life back on an even keel again. He still has a lot to offer South African cricket and his many fans but this has to be done in line with team structures and disciplines."

The first ODI gets underway on Friday at Potchefstroom.
