South Africa will play their final Pool B match hoping to bounce back after narrowly losing in an epic encounter with Ireland.
Having lost their first two matches, Tonga are playing largely for pride, but the Springboks will be keen to bag four or more tries and a bonus point.
That is because they rest the following weekend, when the pool fixtures are completed and Scotland will be hoping to pull off a shock against Ireland and grab one of the two qualifying places for the quarter-finals.
Much of the fallout from the Ireland defeat has been about their misfiring kicking, but director of rugby Rassie Erasmus has defended fly-half Manie Libbok amid calls for his replacement by Handre Pollard.

South Africa flanker Kwagga Smith says it is crucial his team earn a bonus-point win against Tonga after their defeat by Ireland.
“We know we need to get the five points against Tonga, so we will go into the game with the mindset that we need to get a bonus point,” Smith said.
“Tonga are a physical team, so to play against them will be great to know our physicality is also at the highest level. From minute one we need to play hard and take our opportunities.”
Smith also said the Springboks must become more inaccurate, with their kicks and with ball in hand.
“It was a disappointing loss for us [against Ireland], we have reviewed it and we had a lot of opportunities which we did not use. We will have to make sure that doesn’t happen again because from now on, we can’t have any more slip-ups,” Smith said.
“The breakdown is certainly one of those phases where they slowed things down and the ball [came out] one or two seconds slower than it should have. That takes away the chance to score a try.
“But we are excited to know that we created those opportunities and should we play them again, we have to be sharper and use them. That is what we will need to do to win the World Cup.”
