An impressive break from Mark Wilson set up field position for the visitors to reply with his break and Redford Pennycook darted clear from a ruck 25m out to touchdown.

Jimmy Gopperth slotted the conversion and then kicked the Falcons into the lead for the first time with a late first half penalty.

Gopperth had the first word of the second period as well kicking his side further another with another three points.

Lyon then responded with a penalty try converted by Romain Loursac and Laurent Tranier then came off the bench to cross for his side's third try to put them in a commanding position.
