It's a vital few hours for Group B in the men's soccer tournament as all four of the squads go into the last day before knockouts in a tie.

Only the top two teams of each group will advance to knockouts. Argentina, Ukraine, Morocco and Iraq are tied in the standings with 3 points each.

Ukraine is currently playing Argentina, though neither team has scored in the first 30 minutes. Morocco has edged ahead of Iraq with two goals, one by Amir Richardson and another by Soufiane Rahimi.

Coco Gauff’s campaign for Olympic gold ended today after she lost to Croatia’s Donna Vekic.

During the match, a line judge called a ball that landed near the baseline out and Gauff did not keep the ball in play. A chair umpire later ruled the ball had been in, awarding the point to Vekic. Gauff said the timing of the call affected her ability to return, initiating a spat with the umpire.

The scene was a déjà vu. Gauff had an almost identical dispute on the same court months earlier during the French Open, in a semifinal match with Iga Swiatek.

“It isn’t fair,” Gauff said to the official. “It always happens to me on this court. I have to advocate for myself every time.”

Vekic won the first set 7-6 in a tiebreaker and the second set (during which the argument occurred) 6-2.

Egypt beat Spain's national soccer team in Bordeaux this afternoon in a game between the top two countries in men's Group C at the Olympics.

Though both teams were headed to knockouts regardless of the match's results, Spain and Egypt played aggressively down to the last minute of added stoppage time. Egypt led 2-0 toward the end of regular time, but Spanish forward Samu Omorodion scored at the 90-minute mark to put them on the scoreboard.

The Egyptians didn't just want to win; the team played like it wanted to overtake Spain in the standings. They made several attempts at the goal even while in the lead, including an offside by Atef Ahmed, but failed to make it count.

Group C's other matchup for the day, Dominican Republic and Uzbekistan, finished at 1-1. Neither team has enough points to make it to the quarterfinal.

Spain defeated Greece 84-77 in an intense group play game earlier today. Giannis led the charge in the second half to erase Spain's 16-point lead, but it was not enough to overtake Spain's strong shooting, led by Memphis Grizzlies player Santi Aldama.

Greece now sits in last place in its group before playing their final group play game on Friday.

Katie Ledecky comfortably advanced to the 1500-meter free final after reminding us why she is the GOAT in this race.

Finishing nearly 18 seconds ahead of the nearest swimmer, Ledecky was swimming a race of her own. Her time of 15:47.43, however, was measured — she has the world record nearly 40 seconds under that.

In tomorrow's final, we expect another dazzling swim for Ledecky's eighth Olympic gold medal.

China has taken gold for table tennis mixed doubles. The team of Sun Yingsha and Wang Chuqin avenged the country, which had failed to take gold in this event in Tokyo. It was the only table tennis event in which China hadn’t come out victorious, so heavy expectations were sitting on Sun and Wang’s shoulders.

The team defeated North Korea in the final four games to two. This is the first five of table tennis events in Paris. China is the favorite for gold on all five.

Wang walks away with his first Olympic medal. Sun is adding a third to her collection. They will both be competing in the singles and team competitions, too.

China has won 61 of 118 available Olympic medals in table tennis, including 33 gold medals.

This silver is North Korea’s first medal at the Paris Games — and their first Olympic medal since Rio after missing the Tokyo Games due to Covid.

South Korea won bronze, narrowly defeating Hong Kong’s team to walk away with its first table tennis medal in 12 years.

What’s better than skateboarding in Paris? How about skateboarding in Paris with a bronze medal you just won at the Olympics.

That’s what Laguna Beach’s Nyjah Huston did Monday after winning bronze in a highly competitive men’s street final in the French capital. Huston posted a video to Instagram of his skate down a Parisian street, bronze medal in hand, in a moment of solitude after being in the spotlight.

“That was a good moment for me,” Huston said. “After all the media, getting done, getting tested, I was just skating down the street and really just taking in the moment. That video was really the true street skateboarder in me.

“I’m meant to be a skateboarder, and I’m so thankful to be a skateboarder. Obviously, getting stuff like this is great, but just being able to make a living off of what we absolutely love the most is the best part.”

The underdog Americans, following a competitive loss to mighty New Zealand in the rugby sevens semifinal, will play Australia for bronze at 7 p.m. local time (1 p.m. ET).

Before defeating the United States 24-12, the Black Ferns Sevens had scored 119 points in three pool wins before walloping China 55-5 in the quarterfinals.

"New Zealand's not an easy team to score on, so we look at the silver linings," U.S. captain Naya Tapper told NBC News following America's loss to the defending Olympic champions. "We kept them down pretty low compared to the numbers they've been able to put on other teams, and we also put some tries on them. So we're hoping to learn from those and bring that into the bronze medal game."

The Australians won gold in 2016 Rio. Canada will play the Black Ferns for gold.

After Coco Gauff fell in the third round of women's singles, Emma Navarro followed suit, losing to China's Qinwen Zheng 2-1. Like Gauff, this was Navarro's first Olympics.

Danielle Collins will be the only American heading into the quarterfinals of women's singles, after defeating Colombia's Camila Osorio 2-1 earlier today.

Collins, 30, hadn't qualified for the Olympic team until Paris and is set to retire at the end of the year.
