Romeo Romaeo's fourth professional fight, which had been due to take place on Friday, has been cancelled.
Oxhey Village-based Romaeo had been scheduled to face experienced Bulgarian Yordan Vasilev at York Hall in Bethnal Green tomorrow evening.
Original opponent Dai Davies had already pulled out.
However, due to a succession of fighters withdrawing, promoter Mark Prior has been forced to cancel his show.
Speaking earlier today, Prior said: "I'm just really disappointed. I'm pretty confident we would have sold out; we'd sold 1400 tickets in advance.
"I had to cancel unfortunately, I could have made a big loss. When the fighters pull out, they want their money back," explained Prior.
"I wanted to put a good show on at the end of the day," added Prior.
Romaeo is now working towards his next bout against Welshman Lance Sheehan on May 30 in Camden.
The 18-year-old also has fights against Chris Hughes and Craig Woodruff scheduled for later in the year.
Prior also revealed that Romaeo has been doing a lot of sparring recently with other fighters, including 2012 Olympic Gold medallist Luke Campbell and Belfast's Carl Frampton.
