John Hunter Nemechek's Chevrolet Silverado flunked post-race inspection Saturday afternoon at New Hampshire Motor Speedway.
Following his ninth-place finish in the UNOH 175 NASCAR Camping World Truck Series race at NHMS, Nemechek's truck did meet NASCAR's height rules during post-race inspection.
Any penalties handed out likely will come on Wednesday, when NASCAR typically issues its penalty reports.

At the moment, Nemechek is fourth in the Truck Series points standings, but a points penalty would move him down in the standings.
