KANSAS CITY, Kan. — The dozen drivers who advanced to the second round of the NASCAR Cup Series playoffs saw Kansas Speedway as a relatively straightforward test, given the potential chaos looming at Talladega and the unpredictability of the road course at Charlotte. For most of them, it turned out to be a test of survival.

Kyle Larson had a flat on his right rear and scrubbed the wall Sunday early in the first stage of the Hollywood Casino 400 at Kansas Speedway. After bringing out the second caution of the race, Larson told his team the steering was still good in his No. 5 Chevrolet Camaro after getting back on the track. The crash came on Lap 19 of 267.

In Sunday’s race, there were 10 different caution flags that came out and a track record 30 different lead changes during the race, showing just how tricky it can be to win at the speedway.
