Arsenal haver been hit with a £40,000 fine for failing to control their players during the FA Cup third round tie at Oxford United earlier this month.
Gunners players surrounded referee David Coote and appealed for handball in the 34th minute of the match at the Kassam Stadium when a shot from Albert Sambi Lokonga was blocked by Elliott Moore.
Coote pointed for a corner, but was immediately confronted by the angry visiting players.
