Favaro is one of two international back row men banned for next two weeks
Benetton Treviso will be without two key forwards when they face four times champions Toulouse in a vital Pool 2 clash at Stade Ernest Wallon on Sunday.
Italian back row internationals Manoa Vosawai and Simone Favaro were both issued with bans by PRO12 disciplinary panels on Wednesday night following incidents in the recent game against Glasgow Warriors.
Vosawai was given a red card for a dangerous tackle and he was handed a three week suspension. He will be out of action up to and including 27 January, which means he will miss his side's two remaining Heineken Cup matches.
Favaro was cited by former Scotland captain Peter Brown for striking a player with his knee in the same game. He picked up a two week ban that will keep him out of action for up to and including 20 January, ruling him out of the final two European weekends as well. Benetton Treviso host the Ospreys in Round 6.
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.
