NBC 7 looks over the schedule of events from the 2016 Rio Olympics for Sunday, August 21 and brings you seven moments to watch:
1. CLOSING CEREMONY
The first Olympics in South America will come to an end at Maracanã Stadium for the Closing Ceremony. The Mayor of Tokyo, Yuriko Koike, will receive the Olympic flag symbolizing the conclusion of the Rio Olympics and the start to the 2020 Summer Games. Many details are being kept under wraps but look for five-time gymnastics medalist Simone Biles to carry the U.S. flag at the ceremony for Team USA. Norwegian electronic musical Kygo is expected to perform. Brazilian soccer legend Pele, who had hoped to attend the Opening Ceremony before he was sidelined for ill health, could potentially make an appearance on Sunday.

2. US MEN’S BASKETBALL TEAM LOOKS GOLDEN
Local
The U.S. men’s basketball team has had to answer questions about being a disappointment in Olympic competition. But as the U.S. heads into a gold medal showdown with Serbia, who the U.S. defeated 94-91 earlier in the Games, they are the only undefeated team in the tournament at 5-0.
