Bubba Wallace, one of NASCAR's most successful African-American drivers, has condemned Kyle Larson for using a racial slur during an esports event, saying his fellow American needs to get such words "out of his vocabulary."

Larson was suspended indefinitely by NASCAR and dropped by sponsors after he used the racial slur during a livestreamed broadcast of an iRacing esports event on Sunday.

"There is a part of my background and culture that feels attacked and hurt, and the other part feels confused and angry," Wallace, who placed second at the Daytona 500 in 2018, wrote on Twitter on Thursday.
