Tuimoala Lolohea moves to fullback and Matt Allwood comes into the centres for the Warriors' 20th anniversary match against the Brisbane Broncos at Mt Smart Stadium on Sunday (2.00pm kick-off).
With first-choice fullback Sam Tomkins sidelined for four to six weeks with a knee injury, the versatile Lolohea will have his second start in the position in four games this season.
The 20-year-old filled the role in round one against Newcastle when Tomkins was out with a hamstring injury and also played the final 29 minutes against the Eels at fullback last Saturday after Tomkins left the field.
Allwood will become Warrior No. 199 and the seventh player to make his debut for the club this season after Solomone Kata, Ryan Hoffman, Bodene Thompson, Sam Lisone, Albert Vete and Jonathan Wright.
The 22-year-old Allwood signed with the Warriors after making 11 NRL appearances for the Canberra Raiders last season. So far this year he has played twice for the club's New South Wales Cup side - at centre and fullback - as well as being the NRL team's 18th man twice.
"Tui has a big opportunity at fullback with Sam out for a month or so," said assistant coach Tony Iro.
