The Aviva could host Connacht and Dragons in a Champions Cup playoff match and the Pro14 final, as competition organisers contemplate a proposed sprint finish to complete the season.
There are still eight rounds of the tournament left, complicating any attempts to finish the tournament.
The Irish Independent reports that European qualification, the difference between Champions Cup and Challenge Cup, is hugely significant for clubs emerging from this period of financial hardship.
As it stands, Dragons and Connacht would need to play off for a Champions Cup spot so it is conceivable that a double header might be required.
Meanwhile, Leinster and Edinburgh, currently leaders of their respective conferences, could be awarded automatic places in a final under one of several proposals being discussed.
