West Ham United are facing potential punishments for disturbances that broke out around London Stadium in their recent Premier League defeat to Burnley.
The Guardian report that West Ham could be forced into playing their home games in an empty stadium if the crowd trouble that erupted against Burnley is repeated.
The Hammers were 3-0 down to Sean Dyche's side when fighting broke out in the stands and several angry fans invaded the pitch to confront the West Ham players.
Directors David Sullivan and David Gold were advised to leave their seats in the directors' box, as their safety was at risk from angry supporters who had gathered in that part of the stand.
