CHARLOTTE, N.C. — Kyle Busch and Kevin Harvick were fined $25,000 apiece and put on probation Tuesday by NASCAR for their actions on pit road at Darlington Raceway.

The probation for all NASCAR-sanctioned events runs through June 15, a span that includes four Sprint Cup Series championship races and the non-points $1 million All-Star event. It also includes Friday night’s Truck Series race at Dover — an event Harvick only entered after his confrontation with Busch.

Probation is typically no more than a verbal warning that NASCAR will not tolerate any further misconduct during the designated period, and Dale Earnhardt Jr. dismissed the idea either Busch or Harvick will race any differently.

“Probation doesn’t change the way you’re going to drive because you’re still going to drive hard and race as hard as you can,” Earnhardt said Tuesday while promoting the new HD video board at Charlotte Motor Speedway.

“Probation just means it’s obvious when things are intentional and things aren’t. If they go out of the box and do (postrace) things then probation becomes a problem.”

Busch and Harvick’s on-and-off feuding resumed Saturday night after contact Busch had with Harvick led to Harvick wrecking with teammate Clint Bowyer late in the race.

Afterward, Harvick waited for Busch and then positioned himself to park his car in front of Busch on pit road. Busch pulled onto Harvick’s bumper, Harvick climbed from his car and, just as he threw a punch into Busch’s window, Busch used his car to bump Harvick’s car out of the way.
