Bubba Wallace’s test day on the Charlotte Motor Speedway road course ended early when his No. 43 Chevrolet spun and plowed in a Turn 1 tire barrier during the second hour of the test.
The team left the test due to not having a backup car.
Wallace declined to talk to media after his release from the infield medical center.
It was the second caution of the test following a mechanical issue for Chase Elliott that put fluid on the track.
Wallace’s wreck follows his 29th-place finish at Sonoma Raceway last month.
