Rivervalley Rangers are the latest club to make the switch from the Athletic Union League to the Leinster Senior League.
The Swords made the announcement on Tuesday night just days after their season ended with a RTD Ltd Cup win over St Michaels.
The claret and blue sporting outfit finished down the table in Premier B after being relegated from Premier A last term.
While that finish suggests RVR are not an AUL powerhouse there was genuine excitement surrounding the club in recent years and they were a welcome addition to the league.
They now become the first AUL side of the Summer to cross the Dublin divide and they will begin a quest to become an Intermediate outfit from next season on.
Having lost a whopping eight teams-including Collinstown, ST Kevins and Killbarack- after a controversial period last year the AUL was forced into a restructure and did put plans in place to improve the top Dublin junior league.
However, within a matter of days of the AUL league season finishing another club has confirmed it will depart for the LSL.
Rivervalley will be hoping to be placed in Major Sunday 1 the sixth tier of the LSL and two division off Intermediate football, but considering they are coming from Premier B they will most likely be placed lower down the ladder.
