Kevin Harvick and Kyle Busch both were placed on probation for five weeks and fined $25,000 Tuesday for their actions Saturday night following the Sprint Cup race at Darlington Raceway, NASCAR officials confirmed.

Harvick tweeted about the penalties Tuesday morning and NASCAR officials later confirmed that both drivers had been issued the same penalties.

“4 weeks probation and $25,000 fine .... I understand because of the car on pit road,” Harvick said in his tweet.

Both drivers were placed on probation for four Sprint Cup races, plus the May 21 Sprint All-Star race. The probation also applies to all three of NASCAR's national touring series.

Harvick and Busch tangled during the final laps of the Showtime Southern 500, with Harvick spinning after making contact with Busch with less than four laps remaining.

Instead of going to the Sprint Cup garage after the race, Harvick stopped his car near the entrance of pit road with Busch right behind him.

Harvick got out of his car, walked to Busch’s car and tried to punch Busch through the driver’s window. As he attempted to throw the punch, Busch drove away, hitting Harvick’s unmanned car and sending it veering into the pit-road wall close to crewmen.

NASCAR officials summoned both Harvick and Busch to the NASCAR hauler after the race because of the incident on pit road following the event and not for what occurred on the track, according to NASCAR spokesman Kerry Tharp.

“These penalties are a result of what occurred on pit road after the race was over,” Tharp said in a statement Tuesday. “They are about maintaining a safe environment on pit road.”.

Probation typically means that similar incidents, particularly among the drivers involved, could result in harsher penalties. It extends through all NASCAR series, and Busch and Harvick both will be racing in the Camping World Truck Series and Sprint Cup events this weekend at Dover.
