Earnhardt, Jr. has already penned one book, "Driver No. 8", with author Jade Gurss about his rookie season. This book, he says, would be focusing on his battle with concussions and helping others who have suffered head injuries. Earnhardt, Jr. missed the second half of the 2016 season due to concussion symptoms.

Those concerns spilled over to this year, when Dale Jr. said this before racing at Talladega:

"This was one I was worried about, in the back of my mind I was a little concerned,'" Earnhardt said. "You can't win the race if you race scared. I've raced scared here before and you don't do well when that happens, so you have to block it out and take the risks and hope it's not your day to get in one of those accidents and it wasn't."
