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.
HOW TO SEE IT: NBC will air coverage of the Closing Ceremony from 8 p.m. to 10:30 p.m. A one-hour special looking back at the defining moments of the game will air at 7 p.m.
2. US MEN’S BASKETBALL TEAM LOOKS GOLDEN
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.
HOW TO SEE IT: You can see Team USA go for gold live on NBC's daytime coverage or live online at 11:45 a.m. PT.
3. US VOLLEYBALL MEN AIM FOR BRONZE
A little less than 48 hours removed from a shocking loss to Italy in the semifinals, can a young American team rebound to take the bronze from a Russian squad that lost in three sets to Brazil?
HOW TO SEE IT: Catch Team USA take on Russia live on USA Network or live online at 5:30 a.m. PT.
4. CLARESSA SHIELDS FIGHTS FOR BACK-TO-BACK OLYMPIC GOLD

Marial reportedly lost 28 members of his family during Sudan's civil war and escaped slavery before being taken into the U.S. as a refugee.
