Dublin hurling star Ryan O'Dwyer hurt in one-punch England assault
The popular sportsman had been on a short break, with the intention of taking in the Rugby World Cup final at the weekend.
However, he ended up in hospital after being floored by a single punch late on Thursday on a night out.
It has been reported that he was attacked while out socialising and suffered a serious injury.
O'Dwyer (29) is one of the country's best-known hurlers, lining out as centre forward for the Dubs and his local club Kilmacud Crokes.
He is a teacher at a southside secondary school and is married with a baby son.
A source told the Herald that there was an incident in England, and the player was taken to hospital.
"It wasn't a prolonged incident. I think it was one punch and he fell over and hit the ground," the source said.
"They are monitoring him, but they are hoping that he will be fine. He's making progress."
There were reports that the incident happened in the West Midlands, and it was a completely unprovoked attack.
The hurler is believed to have sustained a broken jaw.
Scans were carried out at the hospital where he was taken for treatment.
He was still being treated yesterday.
Supporters took to Twitter and Facebook last night to wish the player a full and speedy recovery.
O'Dwyer, who originally from Tipperary, played for the Cashel King Cormacs club before moving to Dublin.
He played a central role in Dublin's Leinster Championship success in 2013.
Brendan Bonnar, the chairman of Cashel King Cormacs, said he heard O'Dwyer was in Britain for the World Cup match with a friend.
"He is from a well-known, hard-working family in the town," he said.
"His grandfather was a secondary school teacher in the town.
"Ryan is an excellent player, a very dedicated sportsman and determined, and he loves the game.
"Everybody has the highest respect for him and wishes him all the best."
