Cup Series driver Kyle Larson has been suspended by NASCAR and iRacing after he said the N-word during a live stream of an iRacing event Sunday. Chip Ganassi Racing, Chevrolet, McDonalds and Credit One Bank also have terminated their relationships with the 27-year-old.

Apparently not realizing he was speaking to the entire group of drivers on the online simulation rather than just his spotter, Larson can be heard saying, "You can't hear me? Hey, n—."

There was a stunned silence afterward before Anthony Alfredo responded, "Kyle, you're talking to everyone, bud."

Added Aron MacEachern: "Yup, we heard that."

Justin Botelho, the host of the viral stream, said: "Oh damn, he did not just say that."

NASCAR on Monday suspended Larson indefinitely, and CGR had suspended him without pay before announcing Tuesday it had fired him. iRacing also suspended Larson from its service indefinitely.

Credit One Bank and McDonald's, Larson's two primary Cup Series sponsors, announced Monday afternoon they would terminate their relationships with the driver.

Larson apologized in a video to his Twitter followers Monday afternoon.

"I just want to say I'm sorry. Last night, I made a mistake and said the word that should never, ever be said," he said in the video statement. "There's no excuse for that. I wasn't raised that way. It's just an awful thing to say and I feel very sorry for my family, my friends, my partners, the NASCAR community and, especially, the African American community.

"I understand the damage is probably unrepairable and I own up to that. I just want to let you all know how sorry I am. I hope everybody is staying safe during these crazy times."

Larson, a Japanese-American competitor, is a graduate of NASCAR's Drive for Diversity program.

NASCAR's behavior policy states that "NASCAR Members shall not make or cause to be made a public statement and/or communication that criticizes, ridicules, or otherwise disparages another person based upon that person's race, color, creed, national origin, gender, sexual orientation, marital status, religion, race, or handicapping situation.

"Member actions that could result in a fine and/or indefinite suspension, or termination: 1. Public statement and/pr communication that criticizes, ridicules, or otherwise disparages another person based upon that person's race, color, creed, national origin, gender, sexual orientation, marital status, religion, race, or handicapping situation."

In the weeks since the coronavirus pandemic halted live NASCAR events, the sport has held virtual, nationally broadcasted races between drivers on the iRacing simulator, though the virtual race in which Larson participated Sunday was not an official NASCAR iRacing event.
