"More than 10 points could be deducted if the Football League rules that placing the subsidiary company into administration was just a ruse, by stating that one subsidiary company was different from another involving Coventry City.
"If the Football League decrees that this is just about one club, rather than subsidiaries, then Coventry may incur a further punitive deduction."
Though it would have to be at least 20 points to drop them in to the relegation battle.
