CHARLOTTE, N.C. — Kyle Larson was suspended indefinitely by NASCAR and without pay by Chip Ganassi Racing on Monday for using a racial slur on a live stream during a virtual race.

The star driver said there was “no excuse” for his conduct, which drew pushback from sponsors.

NASCAR ordered Larson, who is half Japanese, to complete a sensitivity training course before he’s eligible for reinstatement.

Larson apologized in a video posted on his social media accounts.

“I made a mistake, said the word that should never, ever be said,” Larson said. “There is no excuse for that. I wasn’t raised that way. It is just an awful thing to say. 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. But I just want to let you all know how sorry I am and I hope everyone is staying safe during these crazy times.”

Larson was competing in an iRacing event Sunday night when he appeared to lose communication on his headset with his spotter. During a check of his microphone, he asked his spotter, “You can’t hear me?” That was followed by the N-word. The slur was directed at his spotter, who is white.

iRacing suspended Larson indefinitely Monday for “offensive and inappropriate” language, and the driver could face short- and long-term sponsorship ramifications.

Credit One Bank denounced Larson’s “highly offensive language” and said it supports the “quick actions” by NASCAR and Larson’s team. Chevrolet suspended its pertsonal services relationship.
