Brazil's 10-year absence from the MotoGP calendar will continue this coming season after it was left off the list of races for 2014.
It was hoped a round of the world championship would be staged in Brasilia at the Autodromo Internacional Nelson Piquet circuit on 28 September.
But the venue has not be included on the amended MotoGP schedule for 2014.
MotoGP's last visit to Brazil was in 2004, when the Rio Grand Prix was won by Makoto Tamada.
The omission of Brazil means the San Marino Grand Prix and the Aragon Grand will be two weeks apart, rather than there being races on three consecutive weekends.
The 2014 MotoGP calendar will once again consist of 18 rounds and include a planned new event in Argentina at the Autodromo Termas de Rio Hondo.
