Joe Stimson has been named to join the Country Origin Team as 18th man.
The youngster received a call up from coach Craig Fitzgibbon ahead of Sunday’s City-Country clash.
Stimson has played four NRL games this season since making his debut in Round 2.
The 21-year-old will join Storm teammates Dale Finucane and Cheyse Blair in the side while Josh Addo-Carr will line up opposite the trio after being named on the wing for City.
Melbourne Storm will now have 19 players take part in this week's Representative Round.
