Thomas Carty’s team have claimed “two illegal blows” and “loose ropes” caused the Irishman to topple out of the ring in a bizarre first-round no-contest against David Allen at Croke Park on Saturday.

The co-main event before Katie Taylor’s victory over Flora Pili lasted just one minute and 22 seconds as Carty, who was unable to continue because of a suspected concussion, took a blow to the back of the head.

A statement confirmed Carty, 30, is back home and healthy after spending time in hospital receiving a brain scan.

“After just one minute and 30 seconds of round one, Thomas Carty had received two illegal blows to the back of his head at Croke Park on the Katie Taylor undercard,” the statement said.

“The second blow causing Thomas a momentarily lapse forcing Thomas to reach for the ropes to regain his balance and the loose ropes gave way, propelling Thomas head first out of the ring causing him to strike his head on a ringside table.

“In turn this caused Thomas a suspected concussion and unfortunately an end to this fight on instructions from the ringside doctor.”

Doncaster’s David Allen said on his Youtube channel that he will probably “speak to the boxing board and ask if it can be overturned to a win”.

The 34-year-old claimed he was “a bit too strong and rough” for Carty and said he was likely to win, with the punch that ended the fight not intentional and was aimed to “clip him round the ear”.

“When I’m heavy and fit, he weren’t going to hurt me in a million years. So, I smiled at him and he didn’t like that,” Allen said.

“I’m not aiming for the back of anyone’s head ever, but I am aiming about here [the ear]. It wasn’t a big shot, I tried to clip him round the ear as I always do, and he’s turned his head into it. It’s gone round the back of the head.

“From there on, I don’t know. It’s not for me to say what’s happened. He’s a good guy, I do like him… I’ve caught him behind the head, not on purpose, he’s turned into and he’s gone through the ropes.

“At the time, I said to the referee, ‘are you not going to count?’ If that was in the middle of the ring I’d have won by stoppage. I lost my rag a little and said, ‘look, he’s jumped out the [expletive] ring.’ I couldn’t quite believe it, really, I was a bit shocked.”
