Hunt and Boyd have played together for the Broncos and Queensland
Brisbane Broncos pair Karmichael Hunt and Darius Boyd have been called into Australia's injury-hit World Cup squad.
Wests Tigers full-back Brett Stewart and Brisbane three-quarter Justin Hodges were forced to withdraw because of shoulder injuries.
Hunt, considered unlucky to miss out of the original squad, replaces Stewart.
And Boyd's call-up comes after St George Illawarra centre Matt Cooper was ruled out as a possible replacement because of an injury.
Hunt and Boyd link up the squad despite both being the subject of sexual assault allegations last month.
Queensland Police have concluded an investigation into the claims levelled at the pair and Broncos team-mate Sam Thaiday, and say it will be weeks before it is known if any charges will be pressed.
Coach Ricky Stuart was already without first-choice centre Mark Gasnier, who is now playing rugby union in France, while Anthony Tupou was recalled after Michael Crocker failed to recover from a rib injury.
Tupou had been named in Tonga's squad after the Sydney Roosters forward initially missed the cut for Australia.
The 25-year-old would have required clearance from the sport's governing body to appear for Tonga after winning six caps for Australia.
The World Cup starts in Australia on 25 October.
Holders Australia are in a group with New Zealand, England and Papua New Guinea, with three teams making it through to the semi-finals.
The final will be held in Brisbane on 22 November.
