NASCAR has suspended two crewmen for violating its substance abuse policy, including the former brother-in-law of Jeremy Mayfield.

William David Keith, a spotter for David Gilliland in the Sprint Cup Series, is one of the two crewmen and was suspended Tuesday. Keith is also a former winner in the ARCA Racing Series.

Keith gave a deposition in Mayfield’s legal battle with NASCAR, claiming he witnessed Mayfield using methamphetamines several times. Mayfield became the first driver last May to be suspended under NASCAR’s toughened drug policy.

Matthew Huffstetler was the other crewman suspended. He works for Daisy Ramirez Motorsports in the Camping World Truck series.
