Fireworks erupted at Pocono this weekend, with Kurt Busch harassing Tony Stewart and pit crew after their on track incident.
Kurt Busch, who drives the No. 2 Dodge in NASCAR's Nextel Cup, was fined $100,000 and penalized 100 championship driver points for reckless driving at Dover International Speedway in Delaware earlier this week, NASCAR said in a press release.
The penalty dropped Busch from 11th in the Nextel Cup championship standings to a tie with Bobby Labonte for 18th place.
