Chip Ganassi Racing driver Kyle Larson has been indefinitely suspended from NASCAR following his use of a racial slur on a live stream during an iRacing event Sunday night.

UPDATE: Ganassi parts ways with Larson

The behavioral penalty NASCAR issued Monday cited Sections 12.1 (General Procedures) and 12.8 (NASCAR Member Conduct Guidelines) of the official Rule Book. Larson must also attend sensitivity training as directed by NASCAR.

Larson later posted a video on his social media handles, apologizing for his actions.

The full text: “Hey, I just want to say I’m sorry. Last night I made a mistake and said the word that should never, ever be said. There’s no excuse for that. I wasn’t raised that way. It’s 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 everybody is staying safe during these crazy times. Thank you.”

Earlier Monday, Chip Ganassi Racing officials said in a statement that Larson had been suspended without pay.

“We are extremely disappointed by what Kyle said last night during an iRacing Event,” a statement from Chip Ganassi Racing read. “The words that he chose to use are offensive and unacceptable.

iRacing also released a statement and it read that Larson was suspended indefinitely from the iRacing service.

Section 12.8.1.e in the NASCAR Rule Book states:
