Horne takes centre stage for Kings clash
Horne's return from injury will see Israel Folau return to fullback, while David McDuling moves into the starting line-up in the second row.
Angus Ta’avao will also make his return, after being sidelined for six months when he broke his leg during the National Rugby Championship semifinal.
Andrew Kellaway has been sidelined after sustaining a fracture in a small bone (hyoid) on the weekend playing in club rugby.
