A former bare-knuckle boxer who starred in Channel 4 show Big Fat Gypsy Weddings was the victim of an attack by his cousin, a court has been told.
Paddy Doherty, 51, of Salford, said he did not want to give evidence against Johnny Joyce, accused of attacking him.
Mr Joyce, 20, is alleged to have attacked Mr Doherty at the caravan park where he lives, last August.
At Manchester's Minshull Street Crown Court, Mr Joyce denies causing grievous bodily harm with intent.
Mr Doherty suffered a broken jaw but Mr Joyce claims it was done in self-defence as he suspected he was about to be attacked.
The row stemmed from a dispute at a funeral weeks before, between members of the Doherty and Joyce families, who are from the travelling community, the court has heard.
On Friday, Mr Doherty told the jury: "I have been subpoenaed to come here, I didn't want to come here.
"My wife tried to throw herself off a bridge yesterday.
"Without my wife, I'm nothing. Behind every good man is a good woman."
He said he did not want to return to court to give evidence for a second time as he had "had enough".
Mr Doherty told the court his hard-man image on the Channel 4 documentary was a front for the TV cameras.
Paul Massey, of Salford, was called to give evidence in the case.
Mr Massey said Mr Doherty was the "toughest guy I have ever met".
Michael Lavery, defending Mr Joyce, said Mr Doherty had taken his client back to his house to "do him in".
'Set him up'
He added: "You told Paul Massey you were threatening Johnny Joyce in the minutes up to him hitting you."
But Mr Doherty said he had not threatened anyone and could not remember having a conversation with Mr Massey.
"I wouldn't have been in a position to speak to anyone about what happened," he added.
"I was sleeping all the time, my face was like the Elephant Man's and I wouldn't let anyone look at me."
The case continues.
