Surprise TOP14 front-runners La Rochelle will have the chance to extend their lead at the top of the table when they take-on fellow Challenge Cup quarter-finalists Stade Francais.

La Rochelle, who take-on Edinburgh Rugby at this season’s final venue BT Murrayfield, kickoff a super Saturday of French action at Stade Marcel Deflandre. They take on a Stade Francais side who are looking to replicate the European form that earned them a trip to the Ospreys in the last-eight.

Patrice Colazzo’s men earned a famous 23-20 triumph at RC Toulon last time out to make it five matches without defeat, while Stade are hoping to recover from a 44-22 loss at Grenoble without talisman Sergio Parisse.

European Rugby Champions Cup top-seeds ASM Clermont Auvergne will be hoping to keep the heat on the league leaders with a home triumph over Bayonne. But they will have to do it without their French contingent. Sébastien Vahaamahina starts at lock against Scotland on Sunday while Camille Lopez, Remi Lamerat, Noa Nakaitaci and Scott Spedding will be looking to do damage in the backline.

RC Toulon snuck into the last eight to book a trip to Clermont in the last-eight. But they will be joking to reignite their TOP14 challenge after a damaging 30-6 defeat at Stade Marcel Michelin followed by a home defeat to La Rochelle. They welcome 12th placed Lyon to Stade Mayol.

Toulouse dispatched Connacht at home to earn a mouthwatering trip to Munster in the quarter-finals. They sit sixth, level on points with Toulon, ahead of a tough trip to Challenge Cup champions Montpellier on Sunday.

Fourth place Castres travel to Bordeaux-Begles looking to keep the heat on the top four, while Racing 92 aim to leapfrog Brive. Pau and Grenoble also do battle on Saturday.
