Great Britain welterweight Freddie Evans has admitted that the vociferous home support caused him to lose concentration during his 18-10 win over Ilyas Abbadi.
The Welshman fought well during the three-round contest at the ExCel Arena, but was put through his paces by the Algerian, who caught him with a few decent shots.
The 21-year-old said that the bout should prove ideal preparation for his next encounter.
"I haven't experienced that sort of atmosphere before, with everyone screaming for me, and it put me on a high, it was one big buzz," Evans told BBC Sport.
"The only time I've seen a crowd like that before was at big pro fights.
"I started swinging at times but that was just a bit of ring-rust, and maybe the crowd getting me going a little bit and me getting a bit overexcited. But that should sharpen me up now for the next fight."
Evans will now face Lithuania's Egidijus Kavaliauskas on Friday.
