RIO DE JANEIRO — Brazilian authorities have backed down from a threat to ban flags, musical instruments and shirtless fans from domestic games at the newly refurbished Maracana. However, the use of pyrotechnics and firecrackers will not be allowed, said a statement by Rio de Janeiro state government's sports ministry (Suderj) following a meeting with the police and supporters' groups. Neighbors Fluminense and Vasco da Gama meet Sunday in the Brazilian championship, the first domestic match to be held since the rebuilding of the famous arena. “Fans will be able to take flags with masts up of up to 10 meters, take off their shirts and watch the game standing up,” Suderj said. — AP
