Brazil coach Mano Menezes has not picked Ronaldinho for exhibitions ahead of the London Olympics.
Neymar, Alexandre Pato, Oscar and Paulo Henrique Ganso were among the 23 players summoned for the exhibitions against Denmark on May 26, the United States on May 30, Mexico on June 3 and Argentina on June 9.
The players selected on Friday are expected to form the core of the team that will try to win its first Olympic gold medal. Only six players on the list are older than 23 - David Luiz, Thiago Silva, Jefferson, Daniel Alves, Marcelo and Hulk.
The Olympic tournament is played with under-23 squads but each team can use three over-23 players.
Two-time world player of the year Ronaldinho had been constantly summoned but missed out after bad performances with Flamengo.
