The United States looks to add more swimming medals to its tally, Oksana Masters goes for two golds in two days, and Team USA faces win-or-go-home matchups in wheelchair basketball, goalball and sitting volleyball.

Below is a rundown of what to watch on Day 8 of the Paralympic Games. All events listed below can be streamed live on NBCOlympics.com, and many can also be seen as part of the NBCSN broadcast.

NBCSN will have live coverage of the Tokyo Paralympics from 9 p.m. - 9 a.m. ET. The broadcast will cover lots of different Paralympic events, including the road races in cycling, finals in swimming and track & field, and Team USA's quarterfinal game in men's wheelchair basketball.

Team USA's Oksana Masters won gold in yesterday's time trial to score her first-ever Paralympic medal in road cycling. It's the fourth sport that the versatile summer and winter athlete has won a medal in, having previously earned ones in rowing, biathlon and cross-country skiing. Masters, who had surgery on her leg just 100 days before the start of the Paralympics, will be back on her bike Tuesday night (U.S. time) as she next competes in the women's H5 road race. The women's H5 class is scheduled to start to start its race at 11:15 p.m. ET as one of six classes holding races over the course of the day.

In one of those other road races, defending gold medalist Will Groulx of the United States is one to watch in the men's H1-2 class (8:35 p.m. ET). Groulx competed at the Paralympics in 2004, 2008 and 2012 as a member of the U.S. wheelchair rugby team before qualifying as a cyclist in 2016. He finished just off the podium in fourth place in yesterday's H2 time trial.

Fourteen more medals events take place on this day — five in the first session, nine in the second session.

In the day's first session, American Josh Cinnamo is the reigning world champion in the men's shot put F46 (9:33 p.m. ET) and the current world-record holder. Cinnamo, who was born without a right arm below his elbow, played college football as a kicker. He was introduced to para sports at a talent identification camp in 2014.

The second session includes five different 100m finals, one of which is the women's 100m T54 wheelchair race (7:46 a.m. ET). One American who could reach that final is eight-time medalist Cheri Madsen. Madsen competed at the 1996 and 2000 Paralympics, winning a combined seven medals, before taking a 13-year break from the sport and then coming back to win a silver medal in 2016.

The knockout stage for men's wheelchair basketball gets underway with the quarterfinals. The United States, which finished the group stage at 4-1 and has the best point differential (+115) of any team in the tournament, plays Turkey in the first of those games. With a win, the U.S. men will join the women's team in reaching the semifinals. Both teams are the defending gold medalists in their respective tournaments.

If the U.S. gets past Turkey, it would move on to play the winner of Spain vs. Germany.

Morgan Stickney earned her first Paralympic gold medal yesterday after chasing down Jessica Long to win the women's 400m freestyle S8 final. At the start of the pandemic in 2020, Stickney was recovering from her second leg amputation in two years and relearning how to walk and swim. The yearlong postponement of the Tokyo Paralympics gave her the time she needed to get back in shape and make Team USA.

Now Stickney will join a stacked group of Americans in the women's 50m freestyle S7 field on Day 8. Mallory Weggemann, who has won two gold medals so far in Tokyo, and McKenzie Coan, who has won a gold and a silver, will also be competing in the event. The final is scheduled for 6:36 a.m. ET.

Long will be back in action as well, this time in the women's 100m breaststroke SB7 (4:07 a.m. ET). She's earned one medal of each color thus far at these Paralympic Games to run her all-time count up to 26.

The knockout stage for women's sitting volleyball doesn't officially begin until Friday, but the United States is already faced with an elimination game. Their matchup with the RPC has high stakes for both teams, as they're currently tied with 1-1 records headed into this final match of the preliminary round. The winning team will join China in qualifying for the knockout stage out of Pool B, while the loser will be eliminated from the tournament.

The U.S. women will look to join the men in the goalball semifinals after the men's team dispatched Ukraine in a thrilling sudden-death overtime win yesterday. Amanda Dennis has led the women in scoring in each of Team USA's games so far and will likely be counted on again for the team's quarterfinal matchup against the RPC. A victory would pit the U.S. against the winner of China vs. Brazil in the next round.
