STAMFORD, Conn. – Oct. 8, 2025 – NBC Sports’ live motorsports coverage this week is headlined by two major events: the opening Round of 8 NASCAR Cup Series Playoff race from Las Vegas Motor Speedway, beginning this Sunday at 5:30 p.m. ET on USA Network, and IMSA’s famed Petit Le Mans race from Michelin Raceway Road Atlanta, beginning this Saturday at Noon ET on NBC and Peacock.
NASCAR: LAS VEGAS MOTOR SPEEDWAY
NBC Sports will present live coverage of the NASCAR Cup Series’ opening Round of 8 playoff race with the South Point 400 from Las Vegas Motor Speedway in Las Vegas, Nev., this Sunday, Oct. 12 at 5:30 p.m. ET on USA Network. Live pre-race coverage on USA Network begins at 5 p.m. ET with Countdown to Green. After this race, the final three races of the Cup Series Playoffs will be on NBC and Peacock.
A win in Las Vegas this weekend guarantees a spot in the Championship 4 at the final race in Phoenix on Nov. 2. Shane van Gisbergen won last week’s cutoff race in Charlotte, with defending Cup Series champion Joey Logano passing Ross Chastain after a collision on the last lap to solidify his advancement to the Round of 8 and the chance to defend his title. Denny Hamlin, Ryan Blaney, Kyle Larson, and William Byron make up the current top four. Logano, who currently finds himself below the cutline, is the defending South Point 400 champion, winning two of the last three editions of this race.
NBC Sports’ broadcast team of veteran motorsports play-by-play commentator Leigh Diffey, 21-time Cup Series race winner and “The Mayor” of NASCAR Jeff Burton, and Daytona 500-winning crew chief Steve Letarte will call the action. Marty Snider, Kim Coon, and Dillon Welch will serve as pit reporters.
Marty Snider will host post-race coverage alongside NASCAR Hall of Famer Dale Jarrett and Hyak Motorsports co-owner Brad Daugherty, with Burton joining for pre-race coverage.
Jeff Burton won the Pennzoil 400 at Las Vegas Motor Speedway in back-to-back years in 1999 and 2000.
