More than 91,000 tickets have already been sold ahead of this weekend's Heineken Cup quarter-finals.
Thomond Park - where reigning champions Munster take on the Ospreys - is already a 26,000 sell-out while Cardiff Blues have sold over 29,000 for their clash with triple champions Toulouse at the Millennium Stadium and are on track to smash the current Welsh record of 27,114 for a home Heineken Cup match.
The Blues set that mark in their Round 2 meeting with Gloucester Rugby at the same venue earlier this season.
Tickets sold for the Walkers Stadium showdown between two former Heineken Cup winners, Leicester Tigers and Bath Rugby, have topped the 24,000 mark while Harlequins are just a couple of hundred short of meeting the Twickenham Stoop capacity of 12,638 for the visit of Leinster and are confident of a full house on Sunday.
Tickets can be purchased on match day from the marquee in front of Gate 3 of the Millennium Stadium and from the Welford Road ticket office.
The directors of ERC voted unanimously at a Board meeting to postpone all decisions including the release of further instalments of ERC's distributable central revenues to the six shareholder countries until 19 February next when the Board will meet again to reconsider the issue.
