Florida Gators quarterback Jack Miller has undergone thumb surgery on his throwing hand. It's unclear how long the injury will sideline Miller, an Ohio State transfer who was projected to back up Anthony Richardson going into the season. A third-year sophomore, Miller backed up Justin Fields and C.J. Stroud in two seasons with the Buckeyes, posting 101 yards passing, 29 yards rushing and one rushing TD. The injury is a blow to Florida's depth at quarterback. Redshirt freshman Jalen Kitna, true freshman Max Brown and redshirt sophomore Kyle Engel remain as options to back up Richardson. 📖 more at GatorSports.com ✍: Kevin Brockway / GatorSports 📸: Brad McClenny / Gainesville Sun #floridagators #gogators #gatorsfootball #floridafootball #jackmiller #anthonyrichardson #billynapier #gatorgang
