Sheffield United goalkeeper Paddy Kenny was involved in a brawl with a friend outside a curry house in Halifax in the early hours of Monday morning.
The incident resulted in the Republic of Ireland goalkeeper having his left eyebrow bitten off, sustaining bruising and swelling to the eye.
This latest revelation comes a week after midfielder Alan Quinn paid out £2,000 after admitting being involved in a brawl which left a drinker needing hospital treatment.
Quinn pleaded guilty to affray following a fight over a game of pool in February. A charge of common assault was dropped.
The 27-year-old, also a Republic international, was fined £750 and ordered to pay £750 in court costs and £500 in compensation during a hearing at Sheffield Crown Court.
Last month there were allegations that defender Claude Davis had threatened striker Ade Akinbiyi with a cut-throat razor during a training ground bust-up.
Although Akinbiyi refused to confirm or deny whether Davis had used the razor, he did concede there had been "argy-bargy." The club refused to comment at the time.
But when asked if there were discipline problems at the club, boss Neil Warnock said: "I don't think so.
"But the lads have to learn if you are a professional footballer in the Premier League then you are news.
"There are only Paddy and Alan who have got involved in problems, and they should have been avoided."
Warnock is to speak with Kenny, although he believes the 27-year-old was more sinned against than sinner in relation to the incident earlier this week.
"You obviously don't like things like this, and if Paddy had been the offender then I would be more concerned," remarked Warnock.
"But I don't believe this particular incident was Paddy's fault. His only fault was going out where he shouldn't have done.
"I've told Paddy in the past not to go out in Halifax, and all of a sudden he is back out there. It's not a coincidence.
"He won't be going out in Halifax again. I'll be making my point clear to him on that."
Ironically, if Kenny had been called into the Republic squad that faced San Marino in a Euro 2008 qualifier on Wednesday night, he would not have made front-page news in Ireland.
However manager Steve Staunton opted to leave Kenny out of the squad on this occasion, citing the goalkeeper's reported marital problems.
"I spoke to Paddy on Friday and everything had been going well," said Warnock, who feels confident the player will face Manchester United in Saturday's Premiership game at Bramall Lane.
"People have marital problems and divorces, but he has been coping great with that.
"I've been through one myself, and it's not an easy situation, especially if there are children involved.
"To be fair to Paddy, I think he has done well over the last few weeks. I've been delighted with him.
"But I'm disappointed he has put himself in a position like this, and there's nothing I can do about it unless I start telling him which friends he should and shouldn't be going out with.
"On this occasion he has let himself down, and he has let me down and I think he is more embarrassed about it than anything else.
"But then things happen with young lads like him."
Warnock is hoping Quinn will finally heed his words of advice too, adding: "I've been telling him for a long time to move house to the other side of the city.
"It doesn't need an intelligent person to tell you that if you go out on one of the side of the city and you are an ex-Wednesday player, then you are quite likely to get into trouble.
"Even I can work that out, so I'm hoping he takes it on board.
"But if I thought any of this was affecting the players I would kick them out, make no mistake. You have to have discipline."
