Miller told ESPN on Wednesday that his decision earlier this month to leave the team was based on concerns abuot the long-term effects of head injuries. He said he had one concussion in high school and maybe two to three in college.
“I know I’ve had a few and it’s nice walking away before things could’ve gotten worse,” Miller said. “And yes, multiple schools have reached out. But I’m ready to walk away from it. My health and happiness is more important than a game.”
Miller doesn’t plan to change his mind. He wants to finish his degree and seek business opportunities.
“I know it’s pretty unorthodox for a 21-year-old to see past his own nose,” he said. “This game requires such a passion to excel, and my flame is burned out. However, I’d be lying if I said that the concussion thing doesn’t scare me a little.”
During his career with the Wolverines, Miller played in 22 games and started 16, including all 12 in 2014.
Miller’s decision comes on the heels of San Francisco 49ers linebacker Chris Borland retiring at age 24 after one NFL season because of concussion concerns.
