NASCAR officials threw out the qualifying speeds of both Richard Childress Racing entries Friday after the two cars were found with unapproved alternators at Michigan International Speedway.

The No. 3 Chevrolet of Austin Dillon had qualified seventh and teammate Daniel Hemric’s No. 8 Chevy was 11th in Busch Pole Qualifying for Sunday’s Consumers Energy 400 (3 p.m. ET on NBCSN/NBC Sports App, MRN, SiriusXM). But officials disallowed both qualifying speeds after an inspection revealed the alternator infraction.

In addition, each crew chief will be fined $25,000 and 10 points will be deducted from the driver and owner standings for each team.

The L1-level violations mean the two Richard Childress Racing cars will make up the back row of the 38-car field.

Dillon posted the fastest speed in first practice at the 2-mile Michigan track. Hemric was fifth on the speed chart for the opening session.
