Boyd has made six changes from the starting XV that beat Australia 14-10 in their second pool match played on Monday morning.
In the forwards Boyd Wiggins will get his first start of the tournament at tight-head prop with Sione Mafileo moving to the reserves. There is one further change in the tight five with Christopher Vui starting at lock. Joseph Edwards played on the blindside flank against Australia, and he will move to number eight, making way for Jordan Manihera who will start in the six jersey.
There are three further changes in the backs; Tayler Adams will start at halfback. Two-try hero from the opening match, Michael Collins, comes back into the run-on XV at centre and the final change in the backline is Lolagi Visinia who lines up in the right wing.
Both teams have won their opening two games of the tournament and currently sit on 9 points each.
