When will they ever learn? Kyle Larson will race at Michigan this weekend without his crew chief, who is suspended.
Reason? Larson's car was found to have an improperly installed lug nut.
Chip Ganassi Racing will not appeal the suspension of Chad Johnston, according to a team representative. Expect a replacement chief to be named in the next couple days.
Johnston also was fined $20,000 and placed on probation the remainder of the year, NASCAR disclosed Wednesday in its weekly penalty report.
He is the fourth crew chief suspended since NASCAR began its crackdown on lug nuts at May 1's Kansas race.
