Two play-off contenders will go toe-to-toe as Round 14 of the Top 14 begins with a clash between Stade FranÃ§ais and Grenoble at Stade Jean Bouin.
One of these sides will move up to second spot in the standings on Friday ahead of Saturday's busy schedule, with the Paris side favourites to win.
Stade FranÃ§ais bounced back from a Challenge Cup loss at London Irish a fortnight ago with a home win over the Premiership side last week.
Grenoble meanwhile enter the game on the back of successive defeats to Wasps and will be keen to return to winning ways, particularly as they are just three points off the dream that is the top four.
Friday's travelling side admitted they viewed the Challenge Cup as a chance to rest players so they will be raring to shine after going into the break on the back of a narrow loss at Bayonne.
