Greg Brooks learned he had a brain tumor after weeks of experiencing headaches, nausea, and dizziness. He underwent brain surgery in September 2023.

Brooks Jr. states in the lawsuit that he "passed out" during practice, and "then began to vomit minutes later in front of his coaches and athletic trainers." The lawsuit claims that Brooks Jr. was told by an LSU athletic trainer that he had vertigo and was "cleared to return to practice."

Among a number of eyebrow-raising claims, Brooks Sr. told Good Morning America co-anchor Michael Strahan that Tigers coach Brian Kelly has not reached out to his son since his diagnosis in Oct. '23. "My son almost lost his life. Coach, where were you?" Brooks Sr. said. "Forget about football. Pick up the phone and say you love the kid, man."
