Sheffield United boss Neil Warnock has branded his misbehaving players as 'thick' after goalkeeper Paddy Kenny had his eyebrow bitten at an Indian restaurant.
Kenny was taken to hospital and needed stitches above his left eye.
Warnock insists there is no discipline problem at Bramall Lane but added: 'It's the players who are thick who are causing the problems. They are not going to get their brains back, that's for sure.'
Kenny became embroiled in a brawl with a friend outside a curry house in Halifax in the early hours of Monday.
The latest revelation comes a week after midfielder Alan Quinn paid out £2,000 after admitting being involved in a fight which left someone needing hospital treatment.
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.
When asked if there was a discipline issue at the club, Warnock replied: '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.'
