Tim Payne hs become the second prop to be called up by the British and Irish Lions in four days after concerns about the back injury of his England team mate Andrew Sheridan.
Welshman Gethin Jenkins started at loosehead in the first test loss and looks certain to maintain his place for next Sunday's second test in Pretoria.
The Lions also play the Emerging Springboks in Cape Town on Wenesday in the last of their non-test games.
Last week they called up Ireland's John Hayes to replace Scot Euan Murray, who was ruled out of the tour with an injured ankle.
Hayes and Adam Jones are likely to fight it out for the test starting berth after Phil Vickery was given a torrid time by Springbok man of the match Tendai Mtawarira.
