The United States have made just two changes to their team for Sunday's World Cup Pool A clash with South Africa in Montpellier.
Number eight Dan Payne comes in for Fifita Mounga, who was taken to hospital on Wednesday night after suffering a serious injury in the 25-21 defeat to Samoa in St Etienne.
Mounga, who underwent tests for spinal injuries and had an MRI scan, has regained feeling in his fingers and toes but was not considered for the match against the Springboks.
The other change sees Mike Mangan return to the second row in place of Hayden Mexted.
Coach Peter Thorburn, taking charge of the Americans for the last time, has named an unchanged back-line as the Eagles pursue an unlikely first win in the tournament.
They lost their first three games - against England, Tonga and the Samoans - and have already picked up the group's wooden spoon.
United States team for Sunday's Pool A game against South Africa in Montpellier: C Wyles; T Ngwenya, P Eloff, V Esikia, S Sika; M Hercus (capt), C Erskine; M MacDonald, O Lentz, C Osentowski, A Parker, M Mangan, L Stanfill, T Clever, D Payne.
Replacements: B Burdette, M Moeakiola, M Aylor, H Bloomfield, M Petri, V Malifa, T Palamo.
