Krige has made repeated criticisms of the SARFU in the media

The South African Rugby Football Union said that the flanker is to answer charges relating to an alleged breach of the organisation's Code of Conduct.

Krige began a forthright weekly newspaper column last month and has also been critical in press statements.

Recently he criticised the lack of action taken over the alleged racist incident before last year's World Cup.

Cronje cleared of racism

South African lock Geo Cronje, who is white, was exonerated on Tuesday of any racial motivation after he refused to share a room with black team mate Quinton Davids at a training camp before last year's rugby showpiece.

"This incident put so much pressure on us before and after the World Cup," Krige was quoted as saying.

"Now they say nothing is going to happen. I had sleepless nights about this. I can't believe it."

The former Springbok skipper started his column by explaining why he decided he had to write it.

In his column in the Die Burger newspaper, Krige also questioned the process that led to the appointment of Springbok coach Jake White - the replacement for Rudolf Straeuli, who resigned in December after South Africa's disappointing World Cup campaign.

No date has been set for the hearing yet.
