South Africa have made at least two changes to their pack but will wait until the day before Saturday's four-nations final against Samoa to make decisions on captain Jean de Villiers and flanker Willem Alberts's fitness.
Former Munster centre De Villiers has a chest injury while flanker Alberts must also pass a fitness test on a side strain if he is to feature in the tournament decider in Pretoria.
Jan Serfontein will earn his first start for the Springboks should De Villiers be ruled out as one of up to four changes from the 30-17 win over Scotland.
Siya Kolisi will replace Alberts if the Sharks back row is absent while openside Francois Louw does return after getting married last week.
Second row Flip van der Merwe is listed to start in the second row for Juandre Kruger, who drops to the bench.
"Jean is an integral member of our squad and we will give him all the time he needs to get back to full fitness," said Springbok coach Heyneke Meyer.
"Luckily we have a strong group of leaders in the squad and if Jean doesn't make it, Adriaan (Strauss) will take over the captaincy, with support provided by Francois Louw, Pierre Spies, Bryan Habana and Bismarck du Plessis."
Italy and Scotland will meet in the other match on Saturday with both looking for their first wins of the tournament.
