Argentina v Brazil

The South American rivals will meet in a pivotal game. Each has yet to book a spot in the Quarter-Finals. One win from their last two games will clinch a last-eight place for Argentina while Brazil, who are 1-2, need to get a victory to stay in the hunt.

Spain v Lithuania

A battle of sides that met in last year's EuroBasket Final in France. Lithuania, who lost last year's game, are now 3-0 and can prevent a Spanish side with a No. 2 FIBA World Ranking that has won just one of its three games from moving on. The Spaniards, however, only lost their first two contests to Croatia and Brazil, respectively, in the waning seconds by a combined 3 points.

Croatia v Nigeria

Croatia (2-1), who booked their place in Rio de Janeiro by winning the 2016 FIBA Olympic Qualifying Tournament (OQT) in Turin, will not want to lose their momentum when they face a win-less Nigeria team that still has a chance to advance.
