Friday night’s bill at BT’s base in Stratford, east London, saw London’s Hamzah Sheeraz successfully defend his WBO European super-welterweight title against Scot Paul Kean.
Each fighter was kept in their “bubble” throughout, arriving alongside only their cuts and corner man, with temperature checks and PPE provided for use in the changing rooms.
Each corner was then given a specific zone in which to prepare, while in the ring fighters had their own disposable spit tube, which was replaced between bouts.
Two referees wearing face masks oversaw the five bouts and showered between officiating, with the ring cleaned between fights. Boxers’ gloves and wraps were disposed off in various bins.
The announcer was also stationed outside the ropes and other officials present sat behind a clear screen.
Sports fans have got used to watching events with no crowds but the absence of spectators meant corner calls, as well as the punishing thud of each blow that landed, were clearly audible.
