NASCAR has suspended the Xfinity Series crew chief for Ty Dillon for a penalty at Bristol Motor Speedway.
Nick Harrison was hit Wednesday with a P3 penalty because his Richard Childress Racing entry did not use a proper spoiler assembly and extension.
Harrison was also fined $10,000 and placed on probation through the end of the year.
NASCAR also warned RCR that the car driven by Brandon Jones failed the Laser Inspection Station at Bristol. It's the team's second warning and they will lose 15 minutes of practice time this weekend at Richmond.
