That's a bigger problem for Busch, who is still on track to make the Sprint Cup Chase but who can ill-afford being wrecked in one of the remaining regular season races before the Chase cut-off in September. Newman, on the other hand, has little to lose as he's well out of the top ten and won't be back with the team next season.
"After his comment about me not having a ride, it seems like he has way more to lose than I do," Newman pointed out. "If he's going to run his mouth, he better be able to back up running his mouth."
A few days reflection along those lines might have been part of the reason Busch took to Twitter to clarify his comments and seek to turn down the heat on the row with Newman.
"I want to clarify that I was answering what I felt was two separate questions asked to me at the same time in an interview following the race in Loudon," Busch wrote. "The first was about how fast Kurt was and the second was how I felt about Ryan Newman blaming me for him getting wrecked.
"First I answered the Kurt part. He was fast," he said. "Great to see them running well ... Was a shame to see him crashed ... Nowhere there did I place blame on who wrecked who. I didn't see it and I still haven't seen it.
"My second answer came from being upset over an incident I had with [Newman] on the track during the race. I answered it in the same response, but it was intended as a completely separate answer," he insisted. "I was upset because I felt [Newman] raced me poorly, making contact and causing damage to my [right front] fender that affected the handling on my racecar.
"This isn't the first time that I've been raced poorly by [Newman] either, which added to my frustration," he added. "All this built up and allowed my emotions to spill over for how I felt. I'm not sorry for how I feel in those moments, but could have expressed it better and certainly my comments about someone's livelihood went too far."
Whether Newman is in any frame of mind to let the matter rest at this point remains to be seen. The drivers have a little over a week to cool off before they're back in Sprint Cup action at Indianapolis for the Brickyard 400 on July 28.
