Chad Knaus has a less then stellar reputation - and my guess is that NA$CAR is reminding him that he is a flagrant abuser of the rule book and while what he did probably wouldn't have been so harshly dealt with for another team. Remember, his team of the four that Hendrick 'owns' is the only one busted. The other three passed the inspection just fine. Also, he, personally, might have a less then great relationship with NA$CAR - and NA$CAR is for all intents, owned by the France family. Now as far as him sitting and sweating on the pit box - he will probably be glued to a widescreen monitor in a nice air conditioned motor home in a nearby parking lot or campground and either have phone or radio contact with the pits and/or Johnson during the race. Not a big deal.
