Cox, a sophomore from Stockbridge, Georgia, is listed as a player on Florida's 2019 roster on the athletic department's website as of Saturday. He will have to sit out this season under NCAA transfer rules unless he can obtain a waiver from the NCAA for immediate eligibility. Gators coach Dan Mullen plans to file that waiver and said Monday that he "feels good about" its chances to be successful.
Cox played in 13 of 14 games last season and finished with 20 tackles. He had a career-high six tackles in Georgia's 28-21 loss to Texas in the Allstate Sugar Bowl after starting in place of the injured D'Andre Walker.
"Brenton chose to withdraw from the University of Georgia, go into the transfer portal and he's now at another SEC institution and we wish him nothing but the best and appreciate his contributions while he was here," Georgia coach Kirby Smart told reporters on Saturday.
Georgia defensive coordinator Dan Lanning was asked a week ago about Cox's role this coming season during a news conference. He told the reporter: "That's a good question. I would actually leave that up to Coach Smart at this time."
Cox was arrested in April, along with Bulldogs linebacker Robert Beal, on misdemeanor charges of marijuana possession. Under Georgia Athletic Association policy, he faced a one-game suspension when the No. 3 Bulldogs open the season at Vanderbilt on Aug. 31 (7:30 p.m. ET, SEC Network).
Cox was the No. 11 prospect overall in the 2018 ESPN 300 and the No. 5 defensive end nationally and No. 3 prospect in Georgia.
