Gary Teichmann has confirmed that he will step down from top-flight rugby when his current Newport contract expires at the end of this season.
The 34-year-old former Springboks skipper, who led South Africa on a record 35 occasions, was recruited by Newport's millionaire backer Tony Brown after Nick Mallett sacked him as national captain in July 1999.
Teichmann subsequently took Newport into Europe - they beat Bath and Castres during their debut Heineken Cup campaign - and helped raised the club's profile alongside fellow big-name signings like Franco Smith, Shane Howarth and Adrian Garvey.
"It was a very difficult decision to make, but I have been listening to my body, more than anything else," he said.
