The solution that's been brokered is that Busch will drive but M&M's will not appear on the #18 Cup car, and instead the car will run with sponsorship from Interstate Batteries for the final two races of the year. Interstate has been a sponsor of the team since it began 20 years ago, but is normally a primary sponsor for only about six races per season.
Another of the team's sponsors, Z-Line Designs, has also requested that JGR swap Busch out of the #18 Nationwide Series car next weekend at Homestead and replace him with Denny Hamlin. Busch was never scheduled to run in this weekend's Nationwide race at Phoenix - the #18 will be driven by his JGR team mate Joey Logano this weekend - and nor is there any Camping World Truck race this weekend.
Although cleared to race, Busch was fined $50,000 and is under probation for the remaining NASCAR races of the season, with the additional explicit warning to Busch that any repeat offences will see him 'suspended indefinitely' from racing.
