A Garda investigation into the matter has now concluded and the footballers from the Dublin squad involved in the session won't have to pay fines.
The Irish Times reports that Gardai were satisfied with the engagement of the players during the process of their investigation, which meant fines were deemed not to be a necessary penalty.
The incident resulted in the Dublin county board suspending manager Dessie Farrell for 12 weeks.
Dublin get their Allianz NFL Division 1 campaign underway on Sunday 23rd of May against Kerry in Semple Stadium, Thurles.
