Left winger Jefferson Montero and central midfielder Christian Noboa have overcome muscle injuries to make Ecuador's starting lineup for the Group E match against Switzerland at the World Cup on Sunday.
They were the only lingering injury doubts for either team ahead of the game at Estadio Nacional in the Brazilian capital.
Switzerland will play with its customary 4-2-3-1 formation, with 21-year-old Josep Drmic now the first-choice striker after a strong season with Nuremberg in Germany.
The Swiss are the seeded team in a group that also contains France and Honduras.
Switzerland: Diego Benaglio, Stephan Lichtsteiner, Ricardo Rodriguez, Steve Von Bergen, Johan Djourou, Gokhan Inler, Valon Behrami, Xherdan Shaqiri, Granit Xhaka, Valentin Stocker, Josip Drmic.
Ecuador: Alexander Dominguez, Juan Carlos Paredes, Walter Ayovi, Jorge Guagua, Fricson Erazo, Antonio Valencia, Christian Noboa, Carlos Gruezo, Jefferson Montero, Felipe Caicedo, Enner Valencia.
