Kevin Harvick and Kyle Busch are no longer on probation  for the incident that occurred at the Showtime Southern 500 at Darlington Raceway. Their probation, which spanned four races, ended on June 15th.
While on probation, Busch had an altercation with Richard Childress , owner of Harvick’s No. 29 Sprint Cup Chevy, over a post-race incident with Richard Childress Racing’s Camping World Truck Series driver Joey Coulter. Busch bumped Coulter’s truck on the cool-down lap — a bump he would later call congratulatory.
Childress apparently didn’t like this and was still hot over the fact that Busch turned Harvick’s empty car into the pit road wall  after the Showtime Southern 500. He may have also blamed Busch for an incident with Harvick that resulted in Clint Bowyer (another RCR driver) getting spun into the inside wall at Darlington.
Rumor has it that Childress said, after Darlington, that if Busch touched any more of his equipment, Busch would get a “whuppin.”
The incident did not violate Busch’s probation, as Busch did not fight back.
A week later, during the 5-Hour Energy 500 at Pocono Raceway, Harvick played with Busch on-track , blocking him, running him down to the inside wall, and bump-drafting him down the frontstretch.
NASCAR issued a warning to both drivers. Busch said he wasn’t fighting Harvick, and Harvick said he wanted Busch to know he has one coming.
Being that the Heluva Good! Sour Cream Dips 400 at Michigan International Speedway is the first race since the two drivers came off of probation, there is speculation that we could see some retaliation from Harvick. I doubt that Harvick will do anything to Busch this weekend.
We may see more of what we saw at Pocono, with Harvick racing Busch harder than he normally would. But, I doubt we’ll see Harvick wreck Busch the week after probation. Harvick seems more clever than that.
I think Harvick will wait either until it matters (say, in the Chase or closer to the Chase) or until it has been forgotten about.
I don’t think we’ll see Busch mess with Harvick because Busch probably doesn’t want to lose any more championship points. Busch knows how valuable points are, and he just lost six when his team was penalized for Poconos infractions . So, gaining points has to be the most important thing on his mind.
