South Africa's World Cup organising chief Danny Jordaan may ban vuvuzelas from inside stadiums after complaints from broadcasters and supporters. The constant sound of the high-pitched horn-like instrument has so far drowned out much of the atmosphere-generating singing usually associated with games.

And Jordaan, when asked if he would get rid of them, told BBC Sport: "If there are grounds to do so, yes.

"We did say that if any land on the pitch in anger we will take action."

Jordaan conceded that while the noise was irritating for some people, they were doing all they could to minimise the impact.

"We've tried to get some order," he continued. "We have asked for no vuvuzelas during national anthems or stadium announcements. It's difficult but we're trying to manage the best we can.

"We've had some broadcasters and individuals [complaining] and it's something we are evaluating on an on-going basis."

Jordaan admitted he was not a huge fan of them himself. "I would prefer singing," he said.

"It's always been a great generator of a wonderful atmosphere in stadiums and I would try to encourage them to sing.

"In the days of the struggle (against apartheid) we were singing, all through our history it's our ability to sing that inspired and drove the emotions."
