The series between South Africa and the Lions is heading for a deciding third Test next Saturday.
The Springboks drew level with a 27-9 victory over Warren Gatland's tourists in Cape Town last evening.
Dan Biggar kicked three penalties for the Lions, who failed to score in the second-half.
British and Irish Lions fullback Straurt Hogg has denied allegations he bit a South African opponent yesterday.
Following yesterday's second test defeat to the Springboks, footage emerged of an incident involving Hogg and South Africa fullback Willie Le Roux.
Hogg says he "would never bote an opponent" and says accusations of biting are "unsubstantiated".
