Thomas Costello and Michael Searce were both suspended for four Nationwide Series races and fined $15,000 each Tuesday. They were also placed on probation until the end of the year for the altercation in the motorhome lot after Friday night's race.
Henrico County police charged Searce with two counts of misdemeanor assault, and Costello with one count of misdemeanor assault.
The altercation happened long after Scott and Piquet tangled on pit road after the race. Scott approached Piquet, and Piquet shoved him and kicked Scott in the groin.
Piquet and Scott were placed on probation until June 26, as were their respective crew chiefs.
