NASCAR has suspended Sam Mayer from Saturday's Xfinity Series Championship race at Phoenix Raceway. This comes after the Haas Factory Team driver's contact with Jeb Burton in Martinsville violated the sport's conduct code.

Hendrick Motorsports will go for a record-extending 15th Cup title Sunday (3 p.m. ET on NBC and Peacock) with Kyle Larson and William Byron, the regular season champion, racing for a crown. They’ll go against Joe Gibbs Racing’s Denny Hamlin and Chase Briscoe for the championship.
