The name of the substance is unknown
Former Baby Bok and University of Pretoria captain Zane Botha has quit rugby after testing positive for a banned substance.
This website can reveal, exclusively, that Botha is the Tukkie who has had social media network Twitter abuzz with rumours of a player that tested positive.
However, in contrast to the Twitter-based hype, Botha has quit rugby and has not been involved with the club at all this year.
This website can reveal that Botha was tested in January and when the result returned positive, he informed officials that he was quitting the game.
He has not featured in any of their games this year and is not currently a member of the club.
It has since been reported that he has returned to his hometown of Bloemfontein.
The name of the substance is unknown and it is not clear at this stage if Botha will ever return to the game.
Botha, who captained Tuks to their first Varsity Cup title last year, was born in Bloemfontein and schooled at Grey College.
He moved to the Blue Bulls after school and has represented the Bulls at age-group level and in the Vodacom Cup.
He represented South Africa Under-20 at the 2009 IRB World Junior Championship.
