"Rhys Ruddock would have been selected but has been ruled him out after fracturing his arm against Uruguay last week."
There are just two uncapped players in the 45 – Leinster duo Jack Conan and Tadhg Furlong – while Paul O'Connell will captain the side.
The first warm-up match for Schmidt's squad will be against Wales in Cardiff on August 8.
