France and Toulouse utility back Clément Poitrenaud will miss the first two rounds of the Heineken Cup where Toulouse face Sale Sharks and Harlequins after the double European winner broke his hand in domestic action at the weekend.
As well as losing their free scoring back for up to six weeks, the three time Heineken Cup champions were also knocked off the top of the league table when they lost 17 to 15 to USAP at the Stade Aimé Giral on Saturday.
The ERC Elite 50 Club award winner broke his right hand during the game on Saturday and underwent surgery on the injury on Sunday.
In other Top14 actions Brive and Clermont drew 9-9 on Friday evening while the Montauban v Castres clash was postponed due to restrictions imposed because of swan flue concerns.
Albi were the only team to lose at home over the weekend when they were defeated 9-15 by Toulon. There were home wins for Paris, Racing Metro 92 and even Bourgoin despite their growing financial challenges, who overcame Biarritz.
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.
