"I am continuing to make improvements every day," Busch wrote in a tweet Wednesday. "I know Ty will continue to do a great job representing 23XI and the No. 45 Monster Energy team this weekend in Michigan. I am working hard to get back to 100%, and it’s my hope to be back in the car at Richmond Raceway. Thanks to everyone for the continued support and I look forward to being back on track soon."

Busch appeared at the Charlotte FC match Wednesday. He said doctors told him to seek stimulation, and he was seen banging a drum at Bank of America Stadium.
