The seventh-year quarterback announced on social media Monday night that he played his final game after suffering the fifth concussion of his career. He thanked his teammates and coaches for helping him along the way and assured the Maize and Blue faithful that he won't go far.

“Today I am announcing my retirement from college football. While this decision is difficult, it was made after careful consideration and heartfelt discussions with my family, doctors and loved ones,” the post reads in part. “I want to thank Coach Moore, the staff and my teammates – I love you all. I will continue to help Team 145 as we prepare for the remainder of the season.”
