Brazil have called up Santos forward Gabriel Barbosa to replace suspended captain Neymar in their squad to face Paraguay.
Neymar was booked during Friday's 2-2 World Cup qualifying draw against Uruguay and will miss Brazil's next game of the CONMEBOL section in Asuncion on Tuesday.
Gabriel has represented Brazil and Under-17, Under-20 and Under-23 level and the 19-year-old has been viewed by some as Neymar's potential heir at Santos - the club the Barcelona superstar left when he moved to Spain in 2013.
Corinthians defender Felipe has also been called up by Dunga, as a yellow card for David Luiz against Uruguay means the Paris Saint-Germain centre-back is also ruled out.
Brazil are third in the CONMEBOL standings, with eight points from five matches, placing them above Paraguay and Argentina on goal difference.
