CHARLOTTE, N.C. (AP) -- -

NASCAR has fined Nelson Piquet Jr. $10,000 and ordered him to attend sensitivity training for using an anti-gay slur on social media.

The Nationwide Series driver posted the remark on Instagram Sept. 25 in a post that has since been deleted.

NASCAR also penalized Penske Racing because Joey Logano's race-winning Nationwide car at Dover failed post-race inspection on Saturday.

Crew chief Jeremy Bullins was fined $10,000 and team owner Roger Penske docked six championship car owner points because the car was too low.

Larson to make Sprint Cup debut at Charlotte

Kyle Larson will make his Sprint Cup Series debut next week at Charlotte Motor Speedway driving for Phoenix Racing.
Larson will drive Oct. 12 and he is also scheduled to drive the No. 51 Chevrolet at Martinsville Speedway on Oct. 27.

The two races are a warm-up for Larson as he prepares to move full-time to the Sprint Cup Series next season for Chip Ganassi Racing. He'll drive the No. 42 Chevrolet next season as Juan Pablo Montoya's replacement.

Larson is in his first full NASCAR season this year and ranks ninth in the Nationwide Series. He's got 15 top-10 finishes and is coming off a second-place finish last weekend to Joey Logano at Dover.
