NASCAR has indefinitely suspended the Richard Childress Racing crew member who threw a hammer at driver Kevin Harvick's truck during a race at Martinsville Speedway.

Adam Brown was suspended Thursday specifically for "throwing an object at a competitor's race truck." Crew chief Paul (Marcus) Richmond was fined $10,000 because he assumes responsibility for the entire team. Both work on Ty Dillon's truck for RCR.

Dillon spun Harvick late in Saturday's race as both were racing for position. Harvick hit Dillon's truck under caution, then drove into Dillon's pit stall as he returned to pit road. Brown then threw the hammer at the truck.

Harvick is leaving RCR at the end of the year after 13 seasons.
