On the back of the headliner featuring Anthony Joshua and a British title defence by Frank Buglioni, Thomas v Allen has dropped off the Cardiff Pay-Per-View event on Saturday night.
Joshua was originally due to fight mandatory Kubrat Pulev, who pulled out and was replaced by Carlos Takam, whilst Buglioni’s opponent has now switched from his number one contender Callum Johnson to undefeated Craig Richards.
Promoter Eddie Hearn is frantically searching for a replacement for Thomas, who has gone AWOL and not yet given a reason for not following through with his return with Allen.
Speaking to the Sheffield Star, Allen revealed his disappointment at the current state of affairs.
“I haven’t got a clue what is going on with Thomas,” said Allen.
“I haven’t heard anything from him. We’ve had no correspondence with him at all. “We got ready on the premise of fighting Lenroy Thomas. I got myself in perfect condition. Now I’m very flat.
“Lenroy Thomas on Saturday night was my big world title fight. Getting revenge on him was going to be massive for me.”
Allen went on to explain he may not feature on the Principality show at all.
“It’s not always the best just jumping in with someone else. I did it both times and things didn’t work out that well.
“We’ll just wait and see what they come up with. If any of them make sense then we’ll do it. If not, we’re just going to have to miss out.
“I want to fight on a massive bill but does it make sense for me now? I don’t know.”
