Neymar and Douglas Costa have been included in Brazil's squad for the Rio Olympics.
Stand-in coach Rogerio Micale has named the Barcelona superstar and Bayern Munich forward in his squad as Brazil bid to bounce back from humiliation in the Copa America.
Palmeiras captain and goalkeeper Fernando Prass is the third permitted player over the age of 23 after receiving his first international call-up as a 37-year-old.
Brazil will be playing in their first major tournament on home soil since their embarrassing 7-1 semi-final defeat to Germany.
The Spanish champions allowed Neymar, 24, to play in the Olympics but not this month's Copa America, in which Brazil were knocked out at the group stage.
"Neymar is different. He is one of the best players in the world. Any national team would want to have a player of his profile," Micale said.
"He will mean a lot for the team. I hope he will be able to help the younger players."
Corinthians coach Tite was named as Dunga's successor after he was sacked following Brazil's Copa American exit, but Under-20s coach Micale will be in charge for the Olympics.
The five-time world champions, who face South Africa, Iraq and Denmark in the group stages, have never won the Olympic title and suffered defeat four years ago in London when they lost to Mexico in the final.
