The Republic of Ireland and Poland are facing sanctions from Uefa in the wake of their Euro 2016 qualifier in Dublin.
Martin O'Neill's side have been charged with improper conduct after picking up five yellow cards in Sunday's 1-1 draw.
Wes Hoolahan, John O'Shea, Seamus Coleman, Marc Wilson and James McCarthy were all booked in the Aviva Stadium.
Poland also face disciplinary action after their fans threw objects and set off flares inside the ground on Sunday evening.
A charge of improper conduct is brought automatically when a side is shown five or more yellow cards.
Hoolahan, O'Shea and Coleman were all booked in the first half by Swedish referee Jonas Eriksson, while Wilson and McCarthy were shown yellow cards in the second half of the 1-1 draw.
The sanctions open to Uefa are either a warning or a fine, though any potential fine is likely to be relatively small.
Celtic were fined €8,000 for a similar offence in the Europa League earlier this year.
