St James' Park: Newcastle have banned one of their fans from attending games
The club's head of security, Steve Storey, said in a statement on the club website: 'We are very disappointed that the magistrates did not see fit to support our efforts to try and stamp out racism at football by issuing a banning order.
'But irrespective of this, the club will be banning Hogg from St James' Park for a period of time which is yet to be determined.
'Persistent foul and abusive language is not acceptable at football matches. There is no excuse whatsoever for the use of racist language.
'Such behaviour is a breach of ground regulations, which may lead to ejection and a ban from the ground.
'It also may constitute a criminal offence which may result in arrest, prosecution, a football banning order and a criminal conviction.
'The club is determined to stamp out such behaviour and take firm action against any offending supporter.'
