Uruguay No 8 Carlos Deus, who scored a try when Los Teros beat Namibia in a warm-up match last month, has been recalled to the starting back row for Wednesday's World Cup meeting between the two sides.
Coach Esteban Meneses made one other change to his pack from the 38-17 loss against Italy for the one Pool A fixture both sides have a genuine chance of winning with Diego Arbelo replacing Ignacio Peculo at tighthead prop.
In the backline, centre Felipe Arcos Perez, who also scored a try against Namibia in the warm-up, will play his first match of the tournament in place of Tomas Inciarte, while Bautista Basso comes in on the right wing for Gaston Mieres.
Nine of the starting team played in the 26-18 win over the southern Africans in Montevideo at the start of August.
