Veteran New Zealand kicker Stephen Brett marked his Clermont debut with a last-minute penalty which allowed the French Top 14 title chasers to escape from Bordeaux with a 23-23 draw on Sunday.
The 31-year-old Brett, who only signed for Clermont earlier this month as cover for France international Camille Lopez and the injured Patricio Fernandez, kept his cool with a 30-metre kick to salvage a draw.
But the result was not enough to move Clermont back to the top of the table after they were deposed by La Rochelle 24 hours earlier.
Missing six players away on French international duty, as well as influential centre Wesley Fofana, who has been sidelined by a ruptured Achilles tendon, Clermont were 14-0 down after just 18 minutes on Sunday.
Kiwi loose forward Luke Braid put Bordeaux in front with a try after just seven minutes before scrum-half Yann Lesgourgues added a second on 18 minutes.
Simon Hickey kicked the extras on both occasions for a Bordeaux side looking to end a four-match losing streak in the Top 14 while a Brett penalty was all Clermont had to show for their efforts.
Benson Stanley, a former Blues teammate of Brett's, cut the deficit to 14-10 with a 43rd-minute try for Clermont, converted by Brett.
In a match between two teams, who were facing each other for the eighth time in the last two seasons, the momentum kept swinging.
Hickey made it 17-10 with another penalty before a converted score by lock Sitaleki Timani made it 17-17 with half an hour left.
Hickey and Brett exchanged penalties before Ian Madigan booted a 73rd-minute penalty to edge Bordeaux ahead again at 23-20.
With three minutes left, Brett missed his first kick of the day but held his nerve in the dying seconds when he slotted over the equalising penalty for a share of the spoils.
Toulon president fumes
On Saturday, La Rochelle went top with a 23-20 win at big-spending three-time European champions Toulon.
However, after discussions with head coach Mike Ford, it was agreed that the squad would be back at work from February 5, a full 13 days before their next Top 14 clash against Lyon.
It's understood that the players were already due to return to duty on February 8 but even that was too generous for Boudjellal in the immediate aftermath of a defeat which left fifth-placed Toulon 12 points off La Rochelle.
"I was almost expecting to lose this game," he said. "Holidays are cancelled. I don't care about airline tickets or anything like that, it's their problem."
Toulon weren't the only French giants cut down to size on Saturday as defending champions Racing 92 gave up a 19-13 half-time lead to lose 37-25 to Lyon.
Adding to Racing's problems was the sight of All Blacks star Dan Carter limping off in the 32nd minute with what appeared to be a groin injury.
Defeat left Racing in 10th place, six points off the play-offs while Lyon moved 10 points clear of relegation.
Sixth-placed Toulouse failed to capitalise on Toulon's defeat, suffering a shock 20-10 loss to Pau who have now won four matches in succession.
Castres moved into fourth spot with a 38-25 win over Montpellier, the team above them in third.
Second-bottom Grenoble boosted their survival hopes with a bonus-point 44-22 win over struggling Stade Francais.
