Elliott, who has scored a hat-trick at U21 level, also bagged a brace in the first fixture against Saudi Arabia to secure a 2-1 win for the Irish on Saturday.
Willo Flood has played in both fixtures too while City's Paddy McCarthy and Glenn Whelan also appeared for Ireland against the Saudis.
Ireland now face Mexico on Monday as they look to secure a place in the next stage but yesterday's draw leaves them in a strong position.
