Sha’Carri Richardson has received a one-month suspension after testing positive for marijuana.

The disciplinary action means Richardson will not be able to compete in the 100m in the Tokyo Olympics. The American sprinter’s Olympic-trials-winning time of 10.86 seconds will also be disqualified.

Richardson went on The “Today” Show on Friday to address the suspension, saying, “I apologize.”

The 21-year-old went on to discuss grieving the death of her biological mother during the Olympic trials.

“We all have our different things we deal with, but [I have] to put on a face and have to go out in front of the world and put on a face and hide my pain,” said Richardson.

The American’s Olympic dreams may not be completely dashed. There is still a possibility that USATF will select Richardson to participate in the 4×100-meter relay in Tokyo. That race will take place on Aug. 6, outside of Richardson’s suspension window.

When asked about the possibility of racing in the relay, Richardson expressed gratitude.

“If I’m allowed to receive that blessing, then I’m grateful for it, but if not, right now, I’m just going to focus on myself.”

Athing Mu crushed the 800-meter final at the U.S. Olympic trials on Sunday night, winning the race in 1:56.07.

The 19-year-old’s race, which broke the Olympic trials record, was the second-fastest ever run by an American woman.

Raevyn Rogers and Ajee’ Wilson also qualified for the event, coming in second and third behind Mu.

Gabby Thomas is headed to Tokyo.

The American sprinter put on a show in the 200m final on Saturday, posting a blazing time of 21.61 seconds to speed past the competition and earn a spot on her first Olympic team.

Thomas set a U.S. Olympic track and field trials record with her time. She also clocked the third-fastest 200m ever; only Florence Griffith Joyner has run faster in the race, with times of 21.34 and 21.56 in 1988.

Jenna Prandini and Anavia Battle also qualified for the Olympics, finishing second and third behind Thomas.

Allyson Felix finished fifth and will not be racing in the 200m in Tokyo. Felix will compete in the 400m, which she qualified for earlier in the trials.

Simone Biles leads the competition after day one of the U.S. Olympic gymnastics trials.

Looking to lock up her ticket to Tokyo, Biles dominated the field, holding a 2.899 lead at the end of Friday night. Sunisa Lee, Jordan Chiles and MyKayla Skinner round out the top four in the all-around standings.

Biles, in a league of her own, completed several skills named after herself during the trials. The first being her dismount on beam, as well as two “Biles” skills in her floor routine.

The final Olympic team will be named on Sunday night after the last day of trials airs at 8:00 p.m. ET on NBC.

Allyson Felix is headed to Tokyo.

The 35-year-old sprinter qualified for her fifth Olympics on Sunday with her family, including daughter Camryn, cheering her on.

Felix ran from lane eight in the 400m final, motoring down the race’s home stretch to capture a second-place finish. Her time of 50.2 seconds was a season-best for Felix.

“It has been a fight to get here and one thing I know how to do is fight,” Felix said after the Olympic-qualifying race.

Felix will next race in the 200m at the Olympic trials beginning on Thursday.

Katie Ledecky crushed the competition in the 800 freestyle at the U.S. Olympic swimming trials on Saturday.

Ledecky clocked a time of 8:14.62, finishing five seconds ahead of the field. Her win in the 800 free secured Ledecky her fourth individual Olympic event, qualifying in the 200, 400, and 1,500 as well.

Fifteen-year-old Katie Grimes also booked her ticket to Tokyo, finishing second in the 800 free behind Ledecky at 8:20.36. Grimes shared an emotional embrace with her parents before joining Ledecky in the post-race interview, where the veteran passed the baton to the young phenom, stating Grimes was “the now” of the sport.

Whether or not she’ll admit it, Katie Ledecky has heard the noise from down under.

Australian swimmer Ariarne Titmus fired a warning shot earlier this week, unleashing a 3:56.90 to rattle Ledecky’s world record of 3:56.46 set at the Rio Olympics. It marks the second-fastest time in history.

The fastest Ledecky has been this year – and in a while – has been 3:59.25, set back in April at the Mission Viejo Pro Swim. At the US trials, Ledecky touched in at a 4:01.27 to punch her ticket to Tokyo and make the Olympic team. But it was hardly the warning shot that Titmus sent a couple of days earlier. 

“I thought I’d go a little faster than that, so I was a little surprised,” Ledecky said after the race. “I’ll take it for now.”

While never one to be considered an underdog, Ledecky could very well find herself in the position in both the 200 and 400 freestyles come Tokyo.

“[Ledecky’s] not going to have it all her own way,” Titmus told the Sydney Morning Herald after her own 400 freestyle. “I can’t control what she does, if I do the best I can and put myself in the position to win a gold medal, it’s going to be a tough race.” 

Titmus beat Ledecky in the 400 freestyle at the 2019 World Championships. But that race has been marked by an asterisk, as Ledecky was ill at that meet and wound up missing races. Many dismissed it as a one-time thing.

But Titmus has only gotten faster since then, with her latest time in the event being 1.86 seconds faster than her personal best at those worlds. She then proved her swim in the 400 freestyle wasn’t a fluke by coming within hundredths of the longest-standing women’s world record, set by Frederica Pellegrini in the “super-suit” era, in the 200 freestyle with a time of 1:53.09.  

Ledecky, however, has not given much thought to what’s been going on at the Australian trials.

“I’m not going to be checking results every couple hours or anything,” she said Saturday. “The medals aren’t given this week, so I don’t think we have to get too caught up in what times people are going here versus anywhere else in the world right now.”

Two nights down, two more members of the US Olympic Team.

Torri Huske backed up her night one performance in the 100 fly, breaking her own freshly-minted American Record in the final with a time of 55.66 to punch her ticket to the Olympic Games next month. 

The time puts her second in the world this year and she remains the third-fastest performer in history. 

Second-place finisher Claire Curzan will likely head to Tokyo as well, besting Kate Douglass with a time of 56.43. 

Katie Ledecky officially secured her place in Tokyo in the 400 freestyle, touching in with a time of 4:01.27. She was two seconds faster at the Mission Viejo Pro Swim in April, and even said she thought she had gone faster, but regardless did what she needed to do to make her third Olympic team.

Paige Madden, a three-time individual NCAA champion this past season, took a full second off of her personal best to notch a 4:04.86 and likely make it to Tokyo.

World Record holder Lily King cruised to the top spot in a time of 1:04.72. That time is faster than she was four years ago in Rio, when she swam a 1:04.93 to win gold. 

Her teammate Annie Lazor was equally pumped after clocking in at 1:05.37 to post a best time and the second-fastest time in the world this year.

Lydia Jacoby, who is just 17 years old and came home faster than anyone else in the field, clocked in at 1:05.71 in the heat prior. That time is good for fourth fastest in the world this year and sets up quite the showdown in the final. 

Regan Smith proved that she is the woman to beat heading into tonight’s final in the 100 back, as the 19-year-old clocked in at 57.92. It’s the second sub-58 swim of her career and second only to her world record breaking swim of 57.57 at the 2019 World Championships. That record was recently broken by Kaylee McKeown who swam a 57.45 at the Australian Olympic Trials.

The third night of Olympic trials kicks off at 7 p.m. ET on NBCSports.
