Teenage midfielder Renato Sanches was chosen in the Portugal squad for the European Championship on Tuesday.
The 18-year-old Sanches, who is moving from Benfica to Bayern Munich, has two caps but his standout performances in the Portuguese league earned him a place in the squad that also includes Cristiano Ronaldo.
Sanches received a spot after Monaco midfielder Bernardo Silva was injured last weekend.
Striker Danny and left-back Fabio Coentrao were unavailable with long-term injuries.
Portugal are due to gather in Lisbon on Monday and play friendlies against Norway, England, and Estonia before leaving for France on June 9. They will be in Group F along with Austria, Hungary and Iceland.
Despite producing some of Europe's top players, Portugal have never won any silverware. They were the losing finalists at Euro 2004 on home turf.
The full squad:
Goalkeepers: Rui Patricio (Sporting Lisbon), Anthony Lopes (Lyon), Eduardo (Dinamo Zagreb)
Defenders: Vieirinha (Wolfsburg), Raphael Guerreiro (Lorient), Cedric Soares (Southampton), Eliseu (Benfica), Bruno Alves (Fenerbahce), Jose Fonte (Southampton), Ricardo Carvalho (Monaco), Pepe (Real Madrid)
Midfielders: William Carvalho (Sporting Lisbon), Danilo Pereira (Porto), Joao Moutinho (Monaco), Adrien Silva (Sporting Lisbon), Joao Mario (Sporting Lisbon), Andre Gomes (Valencia), Renato Sanches (Benfica/Bayern Munic)
Forwards: Cristiano Ronaldo (Real Madrid), Eder (Lille), Nani (Fenerbahce), Ricardo Quaresma (Besiktas), Rafa Silva (Braga)
