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