The NASCAR Cup Series’ Mobil 1 301 begins this Sunday, Sept. 21, from New Hampshire Motor Speedway in Loudon, N.H., at 2 p.m. ET on USA Network. Live pre-race coverage on USA Network begins at 1:30 p.m. ET with Countdown to Green.
The first of three races in the Round of 12, this Sunday’s race will see the winning driver clinch their spot into the Round of 8. The last four drivers at the bottom of the playoff standings will be eliminated at the conclusion of the final Round of 12 race on Oct. 5 in Charlotte. Bell is the defending Mobil 1 301 winner, with every winner of this race earning an oversized lobster (usually weighing more than 20 pounds) and posing with it on victory lane.
Christopher Bell won last week’s night race at Bristol Motor Speedway to advance to the Round of 12, while Alex Bowman, Austin Dillon, NASCAR Cup Series Rookie of the Year Shane van Gisbergen and Josh Berry were all eliminated from the playoffs. Denny Hamlin, William Byron, Kyle Larson, Bell, and Ryan Blaney currently sit at the top of the playoff standings, while defending NASCAR Cup Series champion Joey Logano is currently below the cut line.
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 pre-race coverage alongside Letarte, with Diffey hosting post-race coverage with Letarte and Burton.
Burton won at New Hampshire Motor Speedway four consecutive times from 1997-2000, the most wins of any driver in history at that track. Burton led all 300 laps during his win of the Dura Lube 300 on Sept. 17, 2000.
