Ryan Reed, another Chase driver, was scored as being involved, though he did not receive any serious damage.
Wallace was shown wincing as he got out of his No. 6 Ford in the garage.
“Pretty hard hit, just unfortunate,” Wallace told NBCSN. “We were making some good calls and leading some laps and trying to run our own race. People want some wild race in the next three. Here you go. Took out some Chase drivers.”
The Kansas Lottery 300 is the first race in the second round of the Xfinity Chase. The series will be off the next two weeks before resuming at Texas Motor Speedway on Nov. 5.
