Kyle Busch apologizes after using slur in heated post-race interview: 'I used a word I should never use'

Kyle Busch wanted to express his anger with Brad Keselowski. He stooped to using an offensive slur referring to disabled people instead.

"It's frickin' r-------, man, so stupid," Busch said. "I don't understand these guys. I should beat the (expletive) out of (Keselowski) right now, is what I should do, but that doesn't do me any good either."

Busch was upset Keselowski attempted to "spin me out." He later apologized on Twitter.

"In one of my post-race interviews I used a word I should never use and I want to apologize for it," he wrote following a Cup series race at Martinsville Speedway

Fox Sports' Bob Pockrass reported Monday evening that Busch will be required to complete sensitivity training before the start of the 2022 season as the language used is in violation of NASCAR’s conduct guidelines. USA TODAY Sports reached out to NASCAR for further comment.

Kyle Larson was suspended In April 2020 for using a racial slur during an online racing broadcast. NASCAR reinstated him in October of that year, effective Jan. 1, 2021. More recently, Hailie Deegan was fined for using a similar slur as Busch during an iRacing stream in January.

"I already had to pay enough fines in my lifetime," said Busch, who drives for Joe Gibbs racing. "I'm sure I'll get another one."

Busch, a two-time NASCAR Cup Series champion, was eliminated from the 2021 playoffs following Sunday's race at Martinsville Speedway. Larson, who was signed by Hendrick Motorsports following his reinstatement — after being fired from his previous team, Chip Ganassi Racing, for using the racial slur — leads NASCAR with nine wins this season and will race for his first championship Nov. 7 at Phoenix Raceway.
