British boxer Hasnan Ali required an oxygen mask after he was knocked out on his professional debut.
The 22-year-old has been tipped as bright prospect and was on the bill for Charlie Edwards' win over Thomas Essomba on Friday.
He had sold over 300 tickets and was expected to beat Tommy Sams, who took the fight on a 24 hours notice.
However, Sams came out swinging in the first round and caught Ali a number of times, making the former's legs wobble.
He failed to regain his composure and the referee eventually waved off the fight to send shockwaves around the arena.
Ali, who seemed stunned, returned to his corner was attended to by medics and they treated him with an oxygen mask.
The youngster is now in fine condition as he was eventually able to get back to his feet and return to the changing room.
Sams afterwards revealed that he did not prepare for the fight as he was offered it after returning from work just a day before.
He said: 'It was raining all day, I finished work, got home at 2.30pm and got the call. I said yeah I'll take it.
'I was definitely coming for the win. I saw his hands going low so I'd see if he could take [the power].
'I'm buzzing, I feel mint, so proud.'
