Stuart Hogg and Anthony Watson have made way for the Welsh duo whose aerial expertise will be essential to hopes of winning Saturday's series decider at Cape Town Stadium, but in a surprise Duhan van der Merwe keeps his place.

Dan Biggar continues at fly-half but he is rejoined at half-back by Ali Price in a repeat of the partnership that started the first Test. Conor Murray drops to the bench.

Chris Harris is jettisoned at outside centre to make way for Bundee Aki's promotion into the starting XV, with Robbie Henshaw sliding to 13.

Warren Gatland has performed major surgery to his front row in expectation of a renewed set-piece assault from South Africa by bringing in prop Wyn Jones, who has recovered from a shoulder issue, and hooker Ken Owens.

The second and back rows remain unchanged, meaning Alun Wyn Jones continues as captain to make his 12th consecutive Test appearance for the Lions.

All the momentum is with South Africa after they emerged conclusive 27-9 winners from a fractious clash at Cape Town Stadium on Saturday, levelling the series at 1-1.

"The matchday 23 have an incredibly special opportunity in front of them - to seal a Lions series victory in South Africa," Gatland said.

"It doesn't get much bigger than this and we're excited by the challenge that faces us on Saturday.

"We've no excuses from last week, the Springboks put us under pressure in the second half and deserved the win. We have to be much better than that second-half performance and I believe we will be."
