Portugal coach Paulo Bento has included uncapped Braga duo Custodio Castro and Miguel Lopes in his squad for next month's European Championships.
Midfielder Custodio, 28, and 25-year-old defender Lopes are part of a 23-man squad announced by Bento on Monday, which also includes 20-year-old Benfica striker Nelson Oliveira, who has made just one appearance for the senior team.
The squad also includes plenty of familiar names such as Real Madrid trio Cristiano Ronaldo, Pepe and Fabio Coentrao, Manchester United winger Nani and Chelsea midfielder Raul Meireles.
