“This was not an easy decision as I have nothing but the utmost respect for Richard Petty and his family, but I believe it’s time for someone else to take over the reins of the No. 43,” Wallace said in a Twitter post.
“Thank you to the King and everyone at Richard Petty Motorsports for giving me the opportunity to start my Cup Series career. I’ve grown so much as a driver and as a person since joining them. We’ve got nine more races together, and I hope we can finish the 2020 season on a high note.”
RPM confirmed that Wallace will not be returning after the season.
