The grainy footage shows the two boxers in the ring with both being held by the referee before the winner was announced.
The MC can then be heard saying: “Ladies and gentleman, after 10 three-minute rounds of boxing as an official eliminator for the English light heavyweight championship, we go to the referee’s scorecard.
“He scores the contest 95 points to 92 points in favour of your winner, from Newcastle, Scott Westgarth.”
Westgarth then raises his hand in the air as the crowd at the Doncaster Dome wildly celebrate.
But things then took a turn as Westgarth needed paramedics to attend to him in his locker room. He collapsed and was rushed to hospital after looking dizzy and faint in his post-fight conference.
Today it was confirmed he had died in hospital.
Promoter Stefy Bull, who organised Saturday’s event, tweeted: “God bless Scott Westgarth.
“To promote a boxing show and a young man doing a job he loves losing his life I have no words. RIP lad thoughts go out to your family and your team. It’s been the hardest few days I’ve had to endure; no idea what to do moving forward.”
