The family of LSU safety Greg Brooks says the Tigers defensive back has undergone surgery to remove “a large brain tumor.” The family says in a social media post that “doctors successfully performed the procedure” and that biopsy results are pending. Brooks left the team last week just days before the 12th-ranked Tigers’ 41-14 victory at Mississippi State. Coach Brian Kelly said Monday that he could not estimate when Brooks might return to football. Kelly declined to go into specifics about his condition earlier this week because the family was not yet ready to have that information made public. Brooks transferred to LSU from Arkansas before last season. LSU hosts the Razorbacks this Saturday.
