Brad Keselowski and Kyle Busch rekindled their ongoing feud after the two were involved in a crash during the Nationwide Series race at Kansas Speedway on Saturday.
"Now, we got war," was the warning issued by Keselowski after Busch wrecked Keselowski on Lap 188.
The crash came with less than 10 laps remaining and Keselowski finished 28th.
"He's a dirty driver; there's no other way of putting it," Keselowski told reporters. "He's cool with that. I've raced him real cool over the last year to try to be respectful to him and trying to repair our relationship. I've watched him wreck my trucks, cost me from winning races, put me in the fence at Chicago in the truck race. Nationwide races, he's been pulling this crap."
"It's not going to last. I can tell you that. I feel bad for the guys next to me (pointing to the No. 54 hauler). They're going to have to fix his (crap)," he added.
There was buzz surrounding NASCAR officials in recent weeks after several rule changes went into effect after several drivers were accused to trying to manipulate the race results.
NASCAR rules had to be amended in the wake of a race manipulation scandal that has severely impacted the sports credibility after several drivers were found to have acted in a way to unfairly give their team's other drivers an advantage.
NASCAR officials, led by CEO Brian France and President Mike Helton, ordered the drivers to run all-out at all times in order to avoid the perception of impropriety.
"Run 100 percent all the time and you don't have to worry about it," driver Michael McDowell told USA TODAY Sports after the driver's meeting. "That was the gist of it. They said, 'There are lots of things that happen during the race where you have to save fuel or save your stuff.' We get that. We're not looking to hammer anybody. Just race 100 percent. Don't mess with the finish."
