England football's League Managers' Association says Newcastle United football manager Alan Pardew's headbutt on Hull player David Meyler was unacceptable.
The Magpies boss was involved in one of the most extraordinary confrontations in Premier League history when he clashed with Meyler during his side's 4-1 away win at the KC Stadium on Sunday.
Pardew was fined $NZ 200,000 by Newcastle, who stopped short of sacking the fiery Englishman, and seems certain to face disciplinary action from the Football Association.
The Managers' Association chief executive Richard Bevan says the headbutt was unacceptable, inapproptiae and insupportable from every perspective.
Pardew said after the match he would have to sit down and stay out of the way in future rather than roam his technical area to avoid getting caught up in similar incidents in future.
Meanwhile former FA executive director David Davies says it's conceivable that Pardew could be suspended for the rest of the season, adding the incident was a very serious matter which he suspects will be dealt with very severely.
