Organisers hope that Marseille will be able to host them in 2022.
The Heineken Champions Cup and Challenge Cup finals have been taken away from Marseille for a second year.
The French city was due to host both deciders on the 21st and 22nd of May.
Alternative venues are now being sought, with Marseille to return as hosts in 2022.
Meanwhile, Toulouse will be without Rynhardt Elstadt for Saturday’s Heineken Champions Cup clash with Munster.
The South African forward’s fallen victim to quarantine rules, having returned home to take a pilot exam less than a fortnight ago.
E-P-C-R guidelines have been aligned with those of the Irish government which necessitate a two-week quarantine.
Toulouse will fly to Ireland tomorrow which means Elstadt can't travel.
