Williams and Gore will be making their pro boxing debuts. The bout is contracted for 215 pounds and four rounds.
Gore has been training in boxing for years and actually declined advances from NFL teams this season to focus on his first fight. His manager is longtime fight rep Malki Kawa of First Round Management, who also reps NFL players.
Williams is a longtime combat sports enthusiast and has trained for years in mixed martial arts. He’s a part-owner in the highly regarded Fortis MMA gym in Dallas, which is where he will train for this bout under coach Sayif Saud.
Gore, 38, is a five-time Pro Bowl selection and ranks third in NFL history with 16,000 rushing yards. The San Francisco 49ers‘ all-time leading rusher spent 16 seasons in the league, most recently 2020 with the New York Jets.
“I’m excited to be fighting on this card and can’t wait to show the world what I’ve been working on,” Gore said in a statement. “Boxing has me excited, and on Dec. 18 expect fireworks!”
“Combat sports have been a part of my life since my youngest days,” Williams said in a statement. “Before I was a basketball player, I was a wrestler. Since 2015, I have had the privilege of owning an MMA gym, and through that I have trained in various martial arts to stay active. Over the last year, I’ve been waiting for the right opportunity to translate my training into a professional debut.”
Also on the undercard, Amanda Serrano, who is ESPN’s No. 3-ranked pound-for-pound women’s boxer, will take on Miriam Gutierrez.
Serrano is eyeing a high-profile matchup against Katie Taylor in 2022.
