The FAI have been fined €10,000 by UEFA over the tennis ball protest during the Republic of Ireland's Euro 2020 qualifier win over Georgia last month.
Tennis balls rained down on the Lansdowne Road pitch in the 33rd minute of the 26 March qualifier in protest at former FAI CEO John Delaney.
The protest caused a delay, which was immediately followed by Conor Hourihane's winning goal.
It was disclosed two days later that UEFA had charged the FAI over the incident, citing Article 16 (2) of their regulations relating to the throwing of objects.
The disciplinary panel has now hit the FAI with a €10,000 fine as a result, the decision made by the CEDB ('UEFA Control, Ethics and Disciplinary Body').
More dramatic disciplinary action has been taken against Montenegro who will have play their next home game behind closed doors following the racist behaviour of their supporters during their 5-1 loss to England last month.
The FA said a number of England players - including Raheem Sterling, Danny Rose and Callum Hudson-Odoi - were subject to "abhorrent racist chanting" during England's 5-1 Euro 2020 qualifying victory.
UEFA subsequently opened proceedings against Montenegro, including a charge of racist behaviour.
As a result, Montenegro's next qualifier against Kosovo on 7 June will be played behind closed doors and the Football Association of Montenegro must display a banner bearing the message '#EqualGame' at the home game.
They were fined €20,000 for other charges related to the setting off of fireworks, the throwing of objects and crowd disturbances.
