NASCAR indefinitely suspended Kyle Larson, driver of the No. 42 Chevrolet Camaro, for saying a racial slur during an iRacing event Sunday evening. The sanctioning body issued the penalty Monday morning.
NASCAR is also requiring that Larson attend sensitivity training.
During the "Monza Madness" exhibition race at Autodromo Nazionale Monza in Italy on Sunday night, Larson appeared unaware his microphone was being picked up on the stream.
"You can't hear me?" Larson said to his spotter, and then said the slur.
Other drivers immediately erupted in shock.
"Kyle, you're talking to everyone, bud" Xfinity driver Anthony Alfredo said.
"Yep, we heard that," iRacing driver Aron MacEachern said.
"Yikes," IndyCar driver Conor Daly said.
