The return of two star players has boosted three-times Heineken Cup champions Toulouse ahead of their Pool 5 opener against the sold out match against Ulster at Ravenhill…
Jean-Baptiste Elissalde, Toulouse's leading scorer in the competition, and Wales star Gareth Thomas are likely to be available for the match in Belfast, after recovering from injuries.
Benoit Baby, who missed last weekend's Top 14 match with Bayonne along with Thomas, and Omar Hasan and Isitolo Maka are also due to return to full training and will be available for the curtain raiser.
However, Trevor Brennan and Clement Poitrenaud, who picked up injuries during the game at Bayonne, look unlikely to be available for the weekend, while Yannick Nyanga is out with a twisted knee.
Maleli Kunavore, William Servat, Maxime Médard and Frédéric Michalak all have long term injuries, and will definitely miss out.
Meanwhile, Pool 6's Biarritz are likely to be without Imanol Harinordoquy for their opener against Northampton Saints, after he picked up a rib injury in the game against Stade Francais Paris.
Manuel Carrizza and Trevor Hall are also very unlikely to play, after picking up ankle and knee injuries respectively.
However, Biarittz are hopeful that France centre Damien Traille will be available, despite suffering from muscular pain.
Bourgoin have also been hit with injury problems ahead of their Pool 4 opener against Cardiff Blues.
They will be without fullback Glen Davis, wing Jean-François Coux and centre Nicolas Carmona, while brothers Anthony and Mickaël Forest and Mark Rennie have also picked up knocks which put them in doubt for the Blues match
Agen, in Pool 2, will be without Mathieu Barrau, Jack Durling, Kees Meeuws, Lucas Ostiglia and William Stoltz for the match against Edinburgh on Friday night.
And Castres Olympique picked up a number of injuries in their clash with Albi last weekend, leaving Yannick Foriestier (knee), Alex Manta (broken finger) and Gerhard Vooslo (shoulder) very unlikely to play at Wasps
Meanwhile, Castres' Pool 1 rivals Perpignan, will be without the services of Nathan Hines for their match with Benneton Treviso, with the lock missing with a compound fracture of the nose.
