NASCAR has suspended three members of the No. 27 Richard Childress Racing team for intentionally modifying the frame rails of the car Paul Menard drove to a ninth-place finish on Sunday at Michigan International Speedway.

Crew chief Slugger Labbe, car chief Craig Smokstad and crew member Grant Hutchens were each suspended from NASCAR until Oct. 3 and placed on probation until Dec. 31. Labbe was also fined $100,000.

The penalties mean the three will miss the next six NASCAR Sprint Cup races at Bristol, Atlanta, Richmond, Chicago, New Hampshire and Dover.
