RCR crew member who threw sledgehammer at Kevin Harvick’s truck suspended indefinitely

NASCAR announced Thursday that Adam Brown, a Richard Childress Racing crew member for Ty Dillon's team who threw a sledgehammer at Kevin Harvick's truck in Saturday's Camping World Truck Series race at Martinsville,had been suspended indefinitely.

Crew chief Paul Richmond was also fined $10,000.

"The team has been penalized for violating Sections 12-1 (Actions detrimental to stock car racing; throwing an object at a competitor’s race truck) and 9-4A: (The Crew Chief assumes responsibility for the actions of his/her Driver, Truck Owner and team members). The infractions occurred during the race on Saturday, October 26," The NASCAR release said.

"As a result of these violations, crew chief Paul (Marcus) Richmond has been fined $10,000 and crew member Adam Brown has been indefinitely suspended from NASCAR."

After Harvick and Dillon crashed late in the race, Harvick -- who currently drives for RCR in the Sprint Cup Series -- stopped in Dillon's pit box out of frustration. Dillon's crew angrily confronted Harvick to get him out of the way and a sledgehammer came out of nowhere from the direction of the pit box.

When he got out of his truck in the garage, Harvick had some harsh words for the Dillons, saying that they were the reason he was leaving RCR. He later apologized for those remarks Sunday morning before the Sprint Cup Series race.
