Graham Earl has been forced to pull out of his fight with Willie Limond on Saturday after picking up a hand injury in training.
Limond was set to make the first defence of his IBO Intercontinental title in his hometown of Glasgow and the fight will now be rearranged for later in the year.
Earl was going into the contest on the back of successive defeats, the latter a devastating first round knockout to Amir Khan, and does not want to fight if he is not at his best.
"It is a 50-50 fight and I can't afford to go into it at less than 100%," the Luton lightweight said.
"All it would take is my hand to go and my chances of winning would be severely reduced.
"It is really frustrating as I sustained the injury on my last day of hard training before I started to wind my preparations down.
"I thought I might have broken my left hand during sparring and went for an X-ray, but it turned out to be bruising and there is also a lot of swelling."
Limond, who also lost to Khan last year before picking up the IBO strap with victory over Martin Watson, is devastated by the news.
"I'm gutted. My eight weeks of hard training has been for nothing," he said.
"But I realise these things happen and I hope Graham Earl can recover quickly so we can get the fight back on."
