Sylvester Stallone has snubbed his eldest offspring Sage by casting Milo Ventimiglia as his onscreen son in new movie ROCKY BALBOA - the belated sixth installment of the boxing movie franchise.

Sage played ROCKY BALBOA JR in 1990 movie ROCKY V, but the 29-year-old has been replaced by GILMOUR GIRLS star Ventimiglia, 28.

ANTONIO TARVER, Mr T and ROY JONES JR are the pugilists who are expected to go toe-to-toe with Rocky when shooting gets underway next year (06).
