Kid Galahad's promoter Mick Hennessy says plans to get the Sheffield boxer a world title shot later this year have been wrecked by his drugs ban.
Hennessy claims he did not even know about Galahad's two-year ban and had planned for him to fight China's Xiao Jun in Sheffield on July 18. Victory for Galahad - live on free-to-air Channel 5 - would have catapulted him up the WBC rankings from No.7. Jun is No.2 in the WBC rankings with the world champion Leo Santa Cruz expected to relinquish the belt and move up to featherweight.
Galahad, whose real name is Barry Awad, claims that brother Mageed spiked his drink and led to the failed test for banned steroid Stanolozol after his last fight against Adeilson Dos Santos in September 2014.
UK Anti-Doping (UKAD) will consider unbeaten Galahad's appeal in the next few weeks.
Unless Galahad (18-0, 9 KOs) can convince UKAD to lift the ban, his hopes of fighting for a world title and money-spinning fights against British rivals Scott Quigg and Carl Frampton will be in serious doubt.
Hennessy had been hoping to steer Galahad, 25, to a world title shot by the end of the year.
"It was a surprise to me and I only found out just before the news came out," Hennessy told ESPN. "I'm shocked about it and me of all people should have known about it. I've been pushing for his next date and all the time this has been going on.
"I feel for Barry's situation but I found out like everyone else about it. It would have been nice to known sooner because I've been making arrangements.
"I've not been involved with any of it in terms of appealing the ban. An appeal is going in I've been told and the ban has been issued by UKAD. The drugs test was done in September on one of my shows after his last fight, but I've never been notified.
"They thought it [the ban] was going to be thrown out because his brother signed an affidavit and that's why they didn't let anyone know until now.
"It's outrageous if what they are claiming to have happened has happened, a brother doing that to his brother.
"I've been making arrangements with governing bodies and fights. I was doing Barry on July 18 in Sheffield against the WBC silver champion and he was getting close to a world title shot. Now he won't box for the immediate future."
Galahad claims his brother spiked one of his protein shakes with the banned steroid after the pair had a row.
"I didn't know what was going on until a few weeks later I found out a family member had actually spiked me," Galahad told Sky Sports. "It was a malicious act committed in an argument over money.
"I've been tested six times in the last year and passed every single test until my last fight. I am devastated. I'm going to appeal it."
