An unbeaten American boxer landed an uppercut so hard his opponent's body stiffened, losing by instant knockout

• Boxing enjoyed its most significant 24-hour period since being forced to halt operations because of the coronavirus pandemic earlier in the year.
• Three events — in Thailand, England, and the US — all produced headline moments.
• None were as enthralling as Joseph George, an unbeaten American who flattened his opponent with an almighty thump on Showtime Championship Boxing's big return.

An unbeaten American puncher called Joseph George capped a big night for boxing as the sport enjoyed its most significant 24-hour period since returning after a coronavirus-enforced hiatus.

Boxing, like all major sports, was forced to shut down mid-March because of the worsening worldwide spread of COVID-19.

While Top Rank was the first major boxing firm to return, with a summer series behind-closed doors at the MGM Grand Conference Center nicknamed "The Bubble," the Las Vegas-based company is now joined by its rivals.

George, 31, came-from-behind to deliver a knockout of the year contender on the first Premier Boxing Champions event of the COVID-era, before Angelo Leo won the WBO super bantamweight title with a decision victory over Tramaine Williams on Showtime Championship Boxing.

Earlier that night, Matchroom Boxing also held its first pandemic-era event — an outdoor show in the grounds of Matchroom HQ in Essex, a garden county east of London.

Former pound-for-pound staple Srisaket Sor Rungvisai kicked-off Saturday's showdowns with a 120-pound win over Amnat Ruenroeng, a fight which took place in Thailand and was broadcast on YouTube.

"I was setting him up with the jab to the body, I had him leaning over a little," said George. "I was shooting the right uppercut, some landed and some didn't. I wanted him to get comfortable and relaxed … I slipped over and just shot it. It put him down."

Earlier, Matchroom Boxing in the UK returned with influential promoter Eddie Hearn's grand vision — boxing in the back-yard of the mansion in which he lived as a child.

Jordan Gill opened the show with a decision win over Reece Bellotti, Dalton Smith KO'd Nathan Bennett, James Tennyson defeated Gavin Gwynne by stoppage, and Fabio Wardley finished Simon Vallily.

There was no expense spared at Matchroom's event, as the production was high on pyrotechnics and pizzazz.

"Fight Camp" was not the only Matchroom-backed event as Saturday began with a show in Thailand, in which battle-hardened but aging veteran Srisaket Sor Rungvisai out-pointed Amnat Ruenroeng in Thailand.

Yes, with Top Rank, Golden Boy Promotions, Premier Boxing Champions, Queensberry Promotions, and Matchroom Boxing now all back in business, boxing truly feels back — and back with a bang.
