Birmingham have been fined 42 thousand dollars, with a further 42 thousand dollars suspended, following a pitch invasion during their League Cup quarter-final victory over Aston Villa in December.
The club, who went on to win the title, accepted the charge of failing to ensure no spectators or unauthorised persons were permitted to encroach on to the pitch and were handed the punishment by an independent regulatory commission on Tuesday.
More than 1,000 Birmingham supporters invaded the pitch after their side's 2-1 win at St Andrew's and confronted the 3,800 Villa fans at the other end of the stadium.
A flare appeared to be thrown into the section housing the Villa supporters and seats were also ripped out and used as missiles along with other objects.
