Gloucester scrum-half Braley qualifies for Italy through his grandfather, and has been named on the bench for the Azzurri’s Aviva Stadium trip.
The 25-year-old helped England win the Junior World Championships in 2013 and 2014, but has since opted to chase Test rugby with Conor O’Shea’s Italy.
“Saturday will be a big challenge,” said Italy boss and former Ireland full-back O’Shea.
“It will be a great opportunity to shine for many players who want to win a place for the World Cup.”
Benetton tighthead Marco Riccione will make his debut, while flanker Alessandro Zanni will win his 112th cap from the second row.
Italy team to face Ireland in Dublin on Saturday: E Padovani (Zebre), A Esposito, T Benvenuti, M Zanon (all Benetton), G Bisegni, C Canna, G Palazzani (all Zebre), N Quaglio (Benetton), O Fabiani (Zebre), M Riccioni, A Zanni, D Budd (all Benetton, capt), G Licata, M Mbanda, J Tuivaiti (all Zebre). Replacements: F Zani (Benetton), A Lovotti (Zebre), S Ferrari, M Lazzaroni (Benetton), R Giammarioli (Zebre), C Braley (Gloucester), I McKinley (Benetton), M Minozzi (Wasps).
