World Cup organiser mulls vuvuzela ban

Criticism of the vuvuzelas has been almost as loud as the instruments themselves with broadcasting companies complaining the din is almost drowning out commentary.

"We've tried to get some order," said Jordaan.

"We have asked for no vuvuzelas during national anthems or during stadium announcements. I know it's a difficult question," he added, saying that "we're trying to manage the best we can.

"We heard from the broadcasters and individuals and it's something we are evaluating on an on-going base.

Jordaan told the BBC in an interview that he had to consider the option of banning the trumpets.

"If there are grounds to do so, yes," he said, asked if a ban was an option.

France captain Patrice Evra said the incessant noise was a factor in his side's poor display in their draw with Uruguay.
