Phoenix live blog: All the updates from NASCAR Championship Weekend

We‘re bringing you live updates leading up to Sunday’s NASCAR Cup Series Championship at Phoenix Raceway (3 p.m. ET, NBC, MRN, SiriusXM NASCAR Radio, NBC Sports App, Peacock). Bookmark this page and check back often as we chronicle the action from the 1-mile track in the desert.

Overview: 

  • The 1-mile Phoenix Raceway hosts the 312-lap championship race on Sunday afternoon. Leaving the weekend, we‘ll have our 2023 NASCAR Cup Series Champion.

  • Kyle Larson, Christopher Bell, Ryan Blaney and William Byron all escaped the Round of 8 and will compete for the 2023 title.

  • The goal is simple, yet extraordinarily difficult — be the first among the four to take the checkered flag, and you’re the champ.

  • It’s the youngest Championship 4 ever. Larson is the only former champion among them, with Bell the only returner from last year’s title contenders. It’s the first Championship 4 for both Byron and Blaney.

Friday, November 3

8:53 p.m.: Kyle Larson, currently 10th fastest in practice, has been pushing the limits with the outside wall.

8:37 p.m.: AJ Allmendinger has gone for a spin after contact with Kyle Busch. There‘s some minor visible damage on Allmendinger‘s No. 16 car, but it doesn‘t look like anything that‘ll ruin the weekend for either team.
