"As I said earlier today on the SEC Conference Call, Dominique injured his right knee in practice late Tuesday night in a non-contact situation," Florida head coach Will Muschamp said in a statement. "Test results have revealed that he suffered a tear of both his ACL and medial meniscus, which will require season-ending surgery.
"I talked to Dominique and the team this afternoon and we will continue to look for his leadership and experience throughout the season.
"Watching any of your players go through this is one of the hardest things about being a coach. Obviously, it is hardest on Dominique. We are disappointed for him, but we will be there for him every step of the way through his surgery and rehab process."
The only defensive tackles remaining on the roster that have been on the field this year are Darious Cummings, Damien Jacobs and Leon Orr. Florida defensive coordinator D.J. Durkin said on Wednesday that freshmen Jay-nard Bostwick and Joey Ivie could get on the field now, and sophomore defensive end Jonathan Bullard could also slide in as a defensive tackle.
The school also announced that quarterback Jeff Driskel underwent successful surgery on Wednesday to repair his fractured fibula. Driskel had a plate and screws inserted to correct the injury, and doctors also repaired his medial ligaments, putting two screws across his ankle joint.
