Lyon are currently third in Pool 2 and are behind leaders Newcastle and fellow French side Toulon. Petrarca are still looking for their first win in this season's Amlin Challenge Cup.
Toulon v Newcastle Falcons
(Saturday December 17)
Toulon will be looking for revenge when they host Premiership outfit Newcastle Falcons in the return game of the 'double-header' between the two sides at the Stade Felix-Mayol.
The French side suffered a 6-3 defeat to the Falcons last week but need a victory over the English side to keep their hopes of a quarter-finals place in this season's tournament alive.
Toulon, who were beaten finalists in the Amlin Challenge Cup in 2010, know a win in this top of the table clash will put the French side in pole position for the final two games in Pool 2.
