Toulon will travel to Munster for next weekend's Heineken Cup clash without Jonny Wilkinson.

The in-form fly-half injured a knee during Toulon's nervy 19-14 home win against the Ospreys on Saturday, and will now be rested for the Ireland trip.

Although Wilkinson played on - and was integral to Toulon's historic debut win - head coach Philippe Saint-André has opted to rest his star player in order to avoid aggravating the injury.

Wilkinson will now be replaced by experienced Argentine international Felipe Contepomi, who will be returning to play in Ireland for the first time since his transfer from Leinster two summers ago.

Other French teams were also left counting the cost of a bruising first weekend of European action with defending Heineken Cup champions Stade Toulousain concerned over the fitness of hooker William Servat after their narrow 18-16 home win against London Wasps.

French international Servat injured his left thigh in Sunday's win and was forced to leave the pitch, to be replaced by Virgil Lacombe.

Stade coach Guy Noves, meanwhile, has formalized the arrival of Fijian international Rupeni Caucaunibuca, who watched Sunday's win from the stands.

The hugely talented 30-year-old has signed with the European champions until the end of the season after centre Yann David was ruled out for seven months following a double fracture of his right leg in training.

Caucaunibuca has immediately been put on a strict fitness regime to shed his excess pounds, but the eight-time capped international has not been included in Fiji's 30-strong squad to play France (in Nantes on Nov 13), Italy and Wales in the November internationals.

Eight other France-based players have been included though, with Clermont's Napolioni Nalaga, Castres' Sérémaia Bai, Racing's back-row Jone Qovu and La Rochelle duo Norman Ligairi and Seru Rabeni all included from Top 14. ProD2 sides Aurillac, Colomiers and Dax provide the other three with Ropate Ratu, Vereniki Goneva and Saula Radidi all getting the nod from Fiji coach Sam Domoni.

Clermont Auvergne are sweating over the availability of Canadian lock Jamie Cudmore after the combative second row was cited for an alleged stamping incident on Ernst Joubert in their 25-10 home win over Saracens.

Cudmore, who also picked up a yellow card in Saturday's win, could be suspended for between six to eight weeks if found guilty.

Perpignan, who lost 43-34 away to the Scarlets, are also waiting on the fitness of young scrum-half Florian Cazenave after he suffered a bruise shoulder at the weekend. He will undergo further tests this week before seeing if he is fit to take part in their home game against Benetton Treviso on Sunday.

The Catalans are also considering terminating the contract of South African utility back Philip Burger so that he can take up an option to return home and play Super 15 rugby. Burger is currently contracted until 2012 with Perpignan.

There was better news for Biarritz though, with French centre Damien Traille saying he was delighted to get back on the pitch after his second-half cameo during the club's crucial away win in Bath on Sunday.

Traille had not played since last season's Heineken Cup quarter-finals, missing all of this season so far following a summer groin operation.

"I am very glad to be back on the pitch," he said afterwards. "It's a big satisfaction to have played for 20 minutes, even if it was difficult, especially as my kicks were not always well measured." he added.

And while most eyes were trained on European action last weekend there was a full round of ProD2 games in France, with promotion-seeking Lyon OU drawing a staggering crowd of 32,000 for their 'home' match in the Rhone-Alpes derby against Grenoble on Sunday.

The game was switched to Lyon FC's Stade Gerland, with the hosts winning 39-20 to stay in second place behind pace-setters SCA Albi.

Finally, the Ligue Nationale de Rugby (LNR) has confirmed it hopes to host the two Top 14 play-off semi-finals at Marseille's Stade Vélodrome on May 27 and 28. An LNR delegation plans to visit the stadium - used by Toulon for some of its home games - later this month before making a final decision.
