Driver Noah Gragson has been suspended indefinitely from NASCAR's Cup Series race on Sunday due to his actions on social media.

The suspension was a result of Gragson's Instagram account allegedly liking a meme mocking George Floyd, a Black man killed by a White police officer in 2020.

Gragson issued an apology on Twitter, expressing disappointment in himself and acknowledging the severity of the situation.

Legacy Motor Club, Gragson's team, also suspended him indefinitely, stating that his actions do not align with their values.

NASCAR fully supports the suspension and cited that Gragson's social media actions violated the Member Conduct section of the 2023 NASCAR Rule Book.

The suspension prompted NASCAR to replace Gragson with driver Josh Berry for the Cup Series race at Michigan.

CNN has not independently verified the post in question and has reached out to NASCAR for more information.

Gragson, a 25-year-old in his first year in the Cup Series, is currently ranked 33rd in points and has not secured any top-10 finishes this season.

The incident highlights the impact of social media behavior on professional athletes and the importance of adhering to conduct standards set by sports organizations.
