Both Clint Bowyer and Kyle Busch will have fill-in crew chiefs for Saturday night’s Federated Auto Parts 400 at Richmond Raceway.
Greg Zipadelli will fill in for Bowyer and the No. 14 Stewart-Haas Racing Ford team, while Jacob Canter will be interim crew chief for Busch and the No. 18 Joe Gibbs Racing Toyota team. Both team’s regular crew chiefs — John Klausmeier (No. 14) and Adam Stevens (No. 18) — will be suspended for the Richmond race after both cars were missing two lug nuts in post-race inspection on Sunday at Darlington Raceway in the NASCAR Cup Series Playoffs opener.
