Sha'Carri Richardson's name was left off the roster for the 4x100 relay team at the Olympic Games in Tokyo, Japan.

The American sprinter received a 30-day suspension for a failed drug test after she won the 100-meter dash at the U.S. trials in Eugene, Oregon last month.

Richardson tested positive for THC, an ingredient found in marijuana. The positive test meant she would lose her spot on Team USA's 100-meter dash.

The 21-year-old held out hope that she would still be part of the 4x100 relay team since her suspension was up before the start of the relays on Aug. 4.

However, her name was left off the roster USATF released on Tuesday.

Richardson received the bad news over the weekend. She sent out a series of tweets that suggested she didn't take the news well.

Richardson told her followers the Olympic Games will not be the same without her.

"The support [from] my community I thank y'all, the negative [people] forget y'all and enjoy the games because we all know it won't be the same... I'm sorry, I can't be y'all Olympic Champ this year but I promise I'll be your World Champ next year... All these perfect people that know how to live life, I'm glad I'm not one of them!"

American sprinter Sha'Carri Richardson apologized to her fans for failing a drug test, that resulted in a 30-day suspension.

A source tells NBC that Richardson tested positive for THC, the main ingredient in marijuana, after she won the 100-meter dash at the U.S. Olympic trials in Eugene, Oregon last month.

The positive test result means Richardson won't be allowed to compete in the 2020 Tokyo Olympic Games which kicks off on July 23 in Japan.

The 21-year-old Dallas native issued an apology on NBC's "Today" show on Friday morning. "I want to take responsibility for my actions. I know what I did. I know what I'm supposed to do. I know what I'm allowed not to do, and I still made that decision."

Richardson blamed her mother's sudden death last month for her lapse in good judgment. She said learning of her mother's death sent her into a state of "emotional panic."

Richardson, who was raised by her aunt and grandmother, added:

"(I'm) not making an excuse or looking for any empathy in my case, but, however, being in that position in my life, finding out something like that, something that I would say is probably one of the biggest things that have impacted me ... that definitely was a very heavy topic on me. I greatly apologize if I let you guys down, and I did."

She dismissed rumors that she used performance-enhancing steroids. "It's never been a steroid. It will never be a steroid."

"Don't judge me because I am human. I'm you, I just happen to run a little faster."

American sprinter Sha'Carri Richardson may miss the Tokyo Olympic Games this month after she reportedly tested positive for a prohibited substance.

According to The Jamaican Gleaner, Richardson, 21, tested positive for cannabis, aka marijuana, and could miss her chance to win a gold medal at the 2020 Tokyo Olympic Games which kicks off on July 23 in Japan.

Richardson faces a 30-day suspension from international competition.

She has already withdrawn from a track and field meet in Stockholm, where she was scheduled to run in the 200-meter race.

Speculation ran rampant on social media that Richardson tested positive for performance enhancing drugs such as steroids.

However, it was reported by Reuters on Thursday that Richardson tested positive for cannabis at the U.S. Trials in Eugene, Oregon last month.

Richardson won the women's 100-meter dash in 10.86 seconds at the U.S. Trials.

Reuters also reported that the U.S trials' 4th place finisher Jenna Prandini was already asked to fill in the third spot on the USA Olympic team if Richardson is disqualified.

Richardson's agent, Renaldo Nehemiah, former NFL star and record holder in the 110 meters, did not respond to Reuters' request for a comment.

The news prompted anger on social media. Many users questioned why Olympic gold medalist Michael Phelps was allowed to compete in the Olympics after he admitted to smoking marijuana in 2009.

Phelps was suspended for 6 months in February 2009, but his suspension occurred during the off-season.

Donell "DJ" Cooper was suspended by The International Basketball Federation (FIBA) when a urine drug test revealed he was pregnant. Cooper, who was not selected in the 2013 NBA draft, was playing for a pro team in France when his urine test revealed he was with child.
