Following racial tensions within NASCAR, the league’s only full-time Black driver was booed and then subsequently crashed in Wednesday’s race.

Bubba Wallace was booed when introduced during the NASCAR Cup Series All-Star Race, the first event that saw several thousand fans since the league banned Confederate flags, reports Deadline. Despite the ban, numerous Confederate flags were spotted around Bristol Motor Speedway. Wallace had been vocal about his desire for the league to ban the flag. 

During the qualifying race for the main event, Wallace, who drives No. 43, was hit on the right side of the back bumper by driver Michael McDowell. McDowell’s move led to Wallace’s car turning and crashing into the wall, and the damage rendered the vehicle unusable.
