UPDATED 7/2, 9:55 a.m. ET: Sha’Carri Richardson went on the Today show on Friday and spoke about accepting her one-month suspension for marijuana use and being “blinded by emotions” in the wake of her mother’s death.

“I want to take responsibility for my actions,” the 21-year-old said. “I know what I did and what I’m not supposed to do. I know what I’m not allowed to do and I still made that decision. Not making an excuse or looking for any empathy in my case, but being in that position of my life and finding out something like that—something that I would say has impacted my life positively and negatively in my life when it comes to dealing with the relationship with my mother—that definitely was a heavy topic on me.”

Richardson also said she “was definitely triggered and blinded by emotions, blinded by badness, and hurting, and hiding hurt. I know I can’t hide myself, so in some type of way, I was trying to hide my pain.”

Sha’Carri Richardson’s Olympic dreams may be in jeopardy.

According to Jamaica’s Gleaner newspaper, the 21-year-old sprinter tested positive for a prohibited substance during last month’s U.S. Olympic Trials, where she ultimately secured a spot on Team USA. It’s unclear what substance Richardson allegedly consumed, but the outlet points out the infringement could result in a one- to three-month suspension, disqualifying her for the fast-approaching Tokyo Olympics.

Enquirer sports reporter Tyler Dragon cited a source who claims Richardson tested positive for marijuana, rather than steroids. The insider said the athlete is facing a 30-day suspension, which means she could still compete in the 4x100 relay at the Olympics. 

The news comes shortly after Reuters confirmed Richardson would not appear at the Stockholm Diamond League on Sunday, where she was set to compete in the 200m. Her representatives have not explained her absence in this weekend’s event, but a vague tweet has fueled speculation that it was due to Richardson’s purported substance use.

“I am human,” read the tweet, which was posted Thursday afternoon.
