NASCAR Leaders Wreck on Restart Causing Red Flag During Anduril 250 at Naval Base Coronado

A massive wreck has caused a red flag at Naval Base Coronado. This Qualcomm Circuit in San Diego is treacherous. Going into the first turn on a Stage 2 restart, Austin Hill locked up his brakes while on the outside of the front row. That caused a massive pileup.

We are not quite halfway through this Anduril 250, and there are big names missing from the field now. Shane van Gisbergen, Connor Zilisch, Ryan Blaney, and Ty Gibbs were all involved. This is anybody's race now.

This wreck is going to change everything. NASCAR is repairing the wall under the red flag and clearing up fluid off of the track.
