Montauban beat Stade Français 40-35 in Paris while Jonny Wilkinson's Toulon came from behind to beat Clermont 26-21.
Shock victory in Paris on Wednesday evening
Montauban were the big winners on a night of big shocks in the Top 14, beating Stade Français 40-35 in Paris in an epic encounter.
Biarritz also succumbed to a shock defeat, going down 22-18 in Montpellier, and Toulon put one over on Clermont at home again, winning 26-21.
Toulouse took a narrow 21-17 win at home to Bayonne, while Bourgoin, saved from financial ruin on Monday, beat Racing Metro 17-13.
The Albi-Castres clash fell foul of the swine flu sweeping the Castres camp, while Perpignan beat Brive 21-9.
Albi P-P Castres
In the end, seven Castres players were affected by the H1N1 virus as opposed to the six reported last Friday, as well as one of the fitness coaches.
But even though the epidemic is subsiding, the league decided to postpone this match as well as last Saturday's, as Castres had not trained together in over a week.
"For reasons of public health and to beak the chain of the epidemic, the Castres team was not able to come together before Wednesday," explained a league spokesman.
"As a consequence, we have decided to postpone the next two matches of Castres."
Toulon 26-21 Clermont
It all started so well for the visitors, with Seremaia Bai and Anthony Floch both notching penalties - Floch landed two - to give the
Jaunards a 9-0 lead after ten minutes.
Jonny Wilkinson had a rare off-day, missing three penalties as sure as Clermont were landing them in a pugnacious first half which was broken by a huge fight after 20 minutes, strangely not punctuated by any form of card.
The first try came when Wilkinson sent Jamie Robinson through a gap before Sinoti Sinoti finished off in the corner. Wilkinson landed the conversion but Clermont reclaimed the lead just before the break with Bai's second penalty.
Wilkinson missed a drop goal attempt shortly after the break, while Bai made no such mistake with Clermont's fifth penalty. Toulon then scored their second try on 50 minutes when wing Clement Marienval was sent in from five metres on the blind side.
Wilkinson gave Toulon the lead with a majestic touchline conversion, but Bai restored Clermont's advantage with another penalty.
Another penalty miss from Wilkinson on the hour saw the Englishman substituted for Sebastian Fauqué and the replacement promptly landed two beauties - Bai then missing his first of the evening.
Bai pulled it back to 23-21 with eight minutes to go, but Fauqué once again stretched the lead. However, he missed the last kick of the game which could have deprived Clermont the bonus point.
Toulouse 21-17 Bayonne
Bayonne came to defend. They did so extremely well, but eventually came up just short after a rousing second-half comeback by Toulouse.
Bayonne led 14-6 at the break. Jean-Baptiste Elissalde had given the home side a 3-0 lead but Toulouse's open-play kicking game was woeful, epitomised by Elissalde's anodyne kick which gave Lionel Mazars space to send Vilimoni Bolavucu in for Bayonne's opener.
Cedric Garcia converted, but Elissalde pulled a penalty back. Then Freddie Michalak once again showed his fragility, throwing a long looping pass that was picked off by Mazars for a 70-metre intercept try.
Guy Noves had had enough after 50 minutes and sent on five substitutes, including an entire front row. It worked. Within ten minutes Toulouse had scrummed a penalty try out of the opposition.
Michalak gave Toulouse the lead at 16-14 with a penalty, but screwed his conversion attempt of Shaun Sowerby's try horribly, leaving Bayonne within striking distance at 21-14. In the event though, Bayonne could only muster a late Guillaume Bernad penalty.
Montpellier 22-18 Biarritz
After defeat in Bourgoin last week, Biarritz seemed no closer to finding their rhythm this week, although they did outscore Montpellier by two tries to one.
But those two tries came in the final five minutes as the home side eased off the gas, having built up a commanding 22-6 lead with an excellent display. Kicker and fly-half Benoit Paillauge was the hero, landing all his kicks including a conversion of Julien Tomas' 50th-minute try.
Benoit August and Nicolas Brusque were the late Biarritz scorers, but this latest defeat makes it three out of four, not the form of a team that looked dark horses for the title in the pre-season.
Stade Français 35-40 Montauban
It sounds like a try-fest but it really wasn't. Yet the ebb and flow to the scoring and momentum was compelling, as Montauban claimed their first win of the season while Stade succumbed to their third defeat.
Twelve penalties were kicked in all in a match where running rugby was at a premium despite the players' best intentions.
Falie Oelshig and Cedric Rosalen shared four penalties in the first eight minutes alone before Montauban had a threatening move interrupted by Henri Camara's bat-down of the ball. Camara was yellow-carded, Montauban ran the penalty and scored through Bogdan Balan.
Rosalen made it 14-6 with a penalty a minute later, but two Lionel Beauxis drop goals and an Oelschig penalty gave the Parisians the lead back. The kickers traded blows one more time before the break, when Paris led 18-17.
A superb try for Montauban from Viard started the second half, converted by Rosalen, but Oelschig pulled it back to 21-24.
Then Montauban hit their purple patch. First a try for Abdel Boutaty and the conversion extended the lead to 21-31, and two more Rosalen penalties made it 21-37.
Julien Dupuy gave the home side a sniff of a chance, helping Beauxis to a try to make it 28-37, but Rosalen landed yet another penalty to extend the lead once more.
Only Ollie Phillips' late score helped Stade to a bonus point and spared complete humiliation, but questions will be asked in Paris after this display.
Bourgoin 17-13 Racing Metro
Not a great deal to see here in the way of thrilling rugby, but try telling that to the residents of the little market town, who celebrated each move their team made with all the gusto they could muster, as the relief at the club's bail-out spilled over into raw emotion.
Bourgoin were good value for their 14-6 lead - courtesy of a penalty try and one to wing Albert Vulivuli on the hour mark - but Racing fly-half Michel Lorée pulled his side back into it with a well-taken try from a scrum base move.
Benjamin Boyet landed a penalty to ease a few fears that the rescue party celebration would be spoiled and the home side clung on resolutely to win their second of the season.
Perpignan 21-9 Brive
A win for the Catalans and another disappointment for Brive in a disappointing match.
David Marty and Christophe Manas scored early tries which seemed to knock the stuffing out of the visitors, who could muster little beyond penalty shots - and not many of those.
There were also four yellow cards: Christian Short, Andy Goode, Petrisor Toderasc and Gerrie Britz - all either for fighting or dangerous tackles.
