Flamengo took the lead when 17-year-old Vinicius netted from close range at the Maracana stadium on Saturday before Wagner Ferreira equalised with a header, reports Xinhua news agency.
Both Flamengo and Vasco were reduced to nine men after a melee in second-half stoppage time. Flamengo's Rhodolfo and Gustavo Cuellar were sent off, as were Vasco's Breno and Duvier Riascos.
The result left Flamengo second in the 20-team standings with 11 points from six matches, three points ahead of Vasco.
