Clermont claimed their first win of the season with a 21-16 victory over Toulon at Parc des Sports Marcel Michelin on Sunday.
Clermont have now beaten Toulon in back-to-back matches, having won the sides' Top 14 final encounter on June 5.
In the opening quarter, Anthony Belleau and Camille Lopez exchanged penalties as both sides felt each other out.
But in the 17th minute, Chris Ashton set the game alight when he scored his third try of the season in just two games as Anthony Belleau added the extras to give the visitors a 10-3 lead.
However, Toulon's discipline soon cost them when in the space of six minutes just before the interval, Romain Taofifenua and Ma'a Nonu were yellow-carded, leaving their side reeling with 13 men as Lopez added his second penalty to cut the deficit to four.
And Clermont duly capitalised on their numerical advantage when Alivereti Raka scored after the first-half hooter to give the hosts a slender 11-10 lead at the break.
Ten minutes after the interval, Damian Penaud rubbed further salt in to the wounds when he grabbed his first of the season. Lopez added the extras as the home side extended their lead to 18-10.
Clermont were then reduced to 14 men when Peceli Yato was sin-binned with a quarter of the match to go. Belleau slotted a penalty in the 67th minute to cut the deficit to five at 18-13.
The only action of the final 10 minutes saw both fly-halves exchanging penalties as Clermont came away with a vital 21-16 win.
