Brazil has been left off the amended 2014 MotoGP calendar having previously been included for the first time in 10 years.

A first race in Argentina since 1999 stays on the list, however.

Spain's Aragon Grand Prix moves back a week to September 28 to replace the axed Brazil race, which was due to be hosted in

Brasilia.

A MotoGP statement on Monday gave no reason for the Brazil race being removed to leave the calendar at 18 races. Brazil is gearing up to host the 2014 soccer World Cup in June and July but has been beset by problems.

Rio de Janeiro will also hold the 2016 Olympics.
