Greek triple jumper Voula Papachristou was expelled from the Olympics by her country because of a tweet that was deemed racist, according to reports.
"The Hellenic Olympic Committee said her posts mocking African immigrants and expressing support for a far-right party went against the Olympic spirit," reports the BBC.
In a statement, Papachristou apologized and called the tweet an "unfortunate and tasteless joke."
"I would like to express my heartfelt apologies for the unfortunate and tasteless joke I published on my personal Twitter account," the statement said. "I am very sorry and ashamed for the negative responses I triggered, since I never wanted to offend anyone, or to encroach human rights.It is the first time an athlete has been kicked out of the Olympics for social media use.
"My dream is connected to the Olympic Games and I could not possibly participate if I did not respect their values. Therefore, I could never believe in discrimination between human beings and races.
"I would like to apologize to all my friends and fellow athletes, who I may have insulted or shamed, the National Team, as well as the people and companies who support my athletic career. Finally, I would like to apologize to my coach and my family."
