Jamel "Semper Fi" Herring returned to the ring after two COVID-related postponements, defending his WBO junior lightweight world title via eighth-round disqualification over Puerto Rican challenger Jonathan Oquendo at the MGM Grand Conference Center.

Referee Tony Weeks stopped the fight at the conclusion of the round due to repeated intentional headbutts, which left Herring unable to continue.

Herring (22-2, 10 KOs) knocked down Oquendo (31-7, 19 KOs) in the second round, and then the headbutts began. He opened up a nasty gash above Herring's right eye and was deducted a point in the fifth round.

The headbutts continued and ultimately spelled the end of evening for Oquendo. At the time of the disqualification, Herring was in control on the scorecards (80-70 2x and 79-71).

Herring said, “It just got ugly. I wasn’t too satisfied with my performance, to be honest with you. In the beginning, everything was going real smooth, me boxing. I put him down with an uppercut. We knew he was going to come head-first. We had to time it. In the end, I wasn’t happy with how I was looking. I’m disappointed with the outcome. I’ve never been in that situation.

“I still want the Carl Frampton fight next by all means. November, December, whatever. I still want that fight next.”
