The recent news that Sam Horn has chosen to undergo Tommy John surgery to repair his injured throwing elbow means the Tigers are entering spring practice with only two healthy scholarship quarterbacks. With a 12-14 month recovery schedule, Horn’s injury effectively ends his 2024 season before it started, leaving the Tigers with a 6’4 219 lbs hole on their two-deep depth chart. As the cemented second-string quarterback behind starter Brady Cook, Horn’s injury is surely causing consternation among the offensive coaching staff hoping to have a solid back-up plan should Cook suffer an injury of his own next year.
