Cameroon is the only team in Group A that is eliminated from the second round, but they can spoil Brazil's title hopes with a win.

According to FIFA.com, Estadio Nacional in the city of Brasilia will host the match. The arena was built in 2012 and seats 69,349 people. According to Weather.com, conditions should be customarily hot, but there are also expected to be clouds and a chance of rain later in the day.

The easiest way for Brazil to advance to the Round of 16 is to beat Cameroon or finish in a draw, at the least. Brazil can still advance if they lose, but they will need to hope for a result in the Croatia-Mexico match in which the host nation holds the tiebreaker.

The match between Mexico and Croatia also starts at 4 p.m. ET in the city of Recife.

Brazil came into the 2014 World Cup as FIFA's third-ranked team and was heavily favored to compete for the title. They started off strong with a 3-1 win over Croatia, but stumbled slightly in a defensive clinic of a 0-0 draw with Mexico.

The Brazilian national soccer team has made appearances in all of the 20 World Cup tournaments since the inaugural one in 1930. They have also won the title five times.
