With just five rounds of the regular season left to play the jostling in the queue for Top 14 play-off tickets is fiercer than ever.
The clash with the Six Nations this weekend means that many clubs will be without some of their stars. The 'B' champion is also on this weekend, meaning that the Georgian, Romanian and Portuguese internationals are added to the list of absentees.
Clermont are the most severely affected with nine players on international duty making their trip to Castres, who are unbeaten at home, a tough task.
The game of the weekend is in Biarritz, as second-placed Racing roll into town where the hosts will be under pressure to stay in the race for the a top six spot.
The action kicks off on Friday when Perpignan look to continued their rival at home to troubled Bayonne.
Toulouse will have to dig deep into their plentiful resources when they host Brive while Toulon will be looking for a bonus point against Bourgoin.
Relegation candidates Agen and La Rochelle face heavyweight challenges against Stade FranÃ§ais and Montpellier respectively.

USA Perpignan v Aviron Bayonnais
Stade AimÃ© Giral, Perpignan
Bayonne's players did well to steer clear of the club's political battles last week, but with vandals spraying anti-presidential slogans on the stadiums walls, the off-field strife has started to take it's toll with captain Marc Baget admitting they're fed up.
Things are much more positive in Perpignan where the Catalans have launched a late charge to rack up three straight victories to scramble their way back into play-off contention. A loss at home this week however would end those hopes.
After their strong win against Toulouse last week, Bayonne need another big performance to stay ahead of their hosts.
Perpignan welcome back Bertrand Guiry and Joffrey Michel from injury but Henry Tuilagi has been ruled out.
Previous result: Perpignan won 26-25 away
Prediction: USAP's home record is not a be scoffed at. Pepignan by five points
Kick-off: 20:45 (19.45 GMT)
Referee: CÃ©dric Marchat
Biarritz Olympique v Racing-MÃ©tro 92
Parc des Sports d'Aguilera, Biarritz
Biarritz almost threw four points away against La Rochelle last week and can't afford a similar lapse against a Racing side coming off the back of three consecutive wins. On the edge of the European qualification cut off the Basques are under pressure.
Racing meanwhile have been in great form on the road, picking up four wins so far and are looking to secure a top-two finish.
Biarritz have lost just once at home this season but will not be comforted by the memory of Racing's victory at Aguilera last season.
Racing are missing seven international players, including four Italians, and injured Juan Martin Hernandez but their hosts are in the same boat as the core of the BO team will be doing duty for les bleus.
Forwards Erik Lund and Pelu Taele have passed late fitness tests for Biarritz.
Previous result: Racing won 17-12 at home
Prediction: Tough one to call. We'll back the host to edge it. Biarritz by a whisker
Kick-off: 13.50 (12.50 GMT)
Referee: Franck Maciello
Stade FranÃ§ais Paris v SU Agen
Stade CharlÃ©ty, Paris
Stade FranÃ§ais don't have much left to play for after last week's loss to Perpignan. Or do they? The Parisians still have a mathematical possibility of sneaking through the back door and into the knock out stages, but anything less than a bonus-point win will signal the end of their domestic hopes.
Agen on the other hand are still fighting for their Top 14 lives. Having come within a point of winning in Montpellier a week ago, les Agenais will arrive in the capital full of confidence.
Previous result: Stade FranÃ§ais won 27-12 away
Prediction: Can the hosts lift themselves? We think so. Stade FranÃ§ais by five points
Kick-off: 14:00 (13.00 GMT)
Referee: Pascal Gauzere
RC Toulon v CS Bourgoin-Jallieu
Stade Felix Mayol, Toulon
Since charging into the Heineken Cup quarter-finals, Toulon have struggled to repeat that form on the domestic front.
RCT did a lot of attacking for not much reward in Clermont last week but will take heart from an improved performance.
Les Varois need to cut out the mistakes however and a home fixture against the championship's bottom side should be the ideal opportunity to find some rhythm.
They'll do so without Gavin Henson, who having arrived in early February has still yet to make his debut and is not in the team this weekend.
Previous result: Toulon won 26-3 away
Prediction: No surprises here. Toulon to win with a bonus point
Kick-off:14:00 (13.00 GMT)
Referee: SÃ©bastien Minery
Stade Rochelais Atlantique v Montpellier HR
Stade Marcel Deflandre, La Rochelle
After turning heads in the early season, La Rochelle have struggled to maintain that momentum in the new year. Unable to win at home since upsetting Clermont back in November, les Maritimes are back in the relegation zone thanks to a four-match losing streak.
The smallest club in championship came desperately close to snatching a draw in Biarritz last Saturday so there is hope yet.
The task is not easy one however as Montpellier have been the surprise package of the season and are amongst the favourites to make it to the knock out stages.
Fabien GalthiÃ©'s side, who must do without half backs FranÃ§ois Trinh-Duc and Julien Tomas', struggled to get past Agen last week but will back themselves to repeat their easy win over La Rochelle earlier this season.
GalthiÃ© has extended his contract until 2014 an indication that he is unlikely to take over the national team after the World Cup.
Previous result: Montpellier won 26-6 at home
Prediction: It'll be close. Montpellier by three or four points
