Three drivers could use the points provisional to make the main race tonight. In order, they're Ryan Blaney (starting 17th in the Last Chance Qualifier), Kyle Larson (starting 10th) and Ty Gibbs (starting 3rd). John Hunter Nemechek (was to start 12th) is the only driver going to the back for repairs/unapproved adjustments at this point, which will be done at-track this morning without a re-inspection.
As for the field-fillers, Cody Ware is starting the LCQ 14th 12th, Cole Custer is starting 15th, Garrett Smithley is starting 18th 16th and Tim Brown is starting 19th (may be 18th if they move him outside and Nemechek inside as there is no 20th-place LCQ starter). You may object to me calling Custer a field-filler, but that's where SHR (the predecessor to Haas Factory Team) ran much of last year.
The surprising thing is Shane Van Gisbergen raced his way into the main, finishing 3rd in the 2nd heat race (which is where he started) to start 10th tonight.
