Chris Eubank Jr. just joined an exclusive club.

The British middleweight admitted that he “bit” Welsh opponent Liam Williams out of frustration during their 12-round bout held last Saturday at the Motorpoint Arena in Cardiff, Wales, which Eubank won by unanimous decision.

Eubank dropped Williams four times, once each in the first, second, fourth, and 11th round, in what appeared to be a mostly dominant performance. But Eubank also met some adversity along the way, especially in the middle rounds, when Williams had some success taking it to Eubank.

The 32-year-old Eubank (32-2, 23 KOs), however, felt that the 29-year-old Williams (23-4-1, 18 KOs) was trying to roughhouse him by means that were not necessarily legal as per the Marquess of Queensberry.

“We knew he was going to come dirty,” Eubank told reporters in the post-fight press conference. “We knew he was going to try everything he could to take the fight to me, whether it was in or out of the rules of boxing. We dealt with it. I didn’t complain.

“I’m upset the referee didn’t take a point – at least one – for the amount of headlocks, headbutts, and everything that was going on. He was pushing his hand up into my face a couple of times. I actually had to bite him at one point.”

The most famous boxer to employ his fangs inside the ring is, of course, Mike Tyson, who tore off the ear of Evander Holyfield in their heavyweight title rematch in 1997. Floyd Mayweather Jr., to mention another example, once accused Marcos Maidana of biting his hand during their welterweight rematch in 2014.

“I’ve never bitten anybody in the ring before,” Eubank said. “I bit him. He put his arm around my neck, squeezing my neck, his glove was kind of close to my mouth, so I gave it a bite as hard as I could.

“If he’s going to fight dirty, I’m going to fight dirty. It is what it is, but it was a fun fight.”

Eubank won on scorecards that read 116-109, 116-108 and 117-109, giving him his sixth straight win since his points loss to George Groves in 2018 in their super middleweight bout.

This was Williams' second loss in a row. His last bout was a loss to WBO middleweight titleholder Demetrius Andrade in April.
