Leinster Rugby confirmed this morning that all 18,400 seats in the RDS sold out over the weekend.
Ulster Rugby also took their full allocation and returned no tickets for general sale.
As a result an additional 700 seats were installed over the weekend and these also sold out by 10am on Monday morning bringing the total attendance for the first of the Guinness PRO12 Play-Offs to 19,100.
Leinster Rugby and the RDS would like to remind supporters that there are three other events in the RDS on Friday evening and that car parking will be at a premium. As a result we would strongly advise that supporters use public transport to and from the game.
