Leinster team news?
Leinster have rung the changes after their recent PRO14 win over Connacht. The likes of Robbie Henshaw, Ross Byrne, Cian Healy, Devin Toner, and Scott Fardy all return to the starting XV.
Here's the team in full:
Leinster Team: Jordan Larmour; Dave Kearney, Garry Ringrose, Robbie Henshaw, James Lowe; Ross Byrne; Luke McGrath, Cian Healy, James Tracy, Tadhg Furlong; Devin Toner, Scott Fardy (Capt); Rhys Ruddock, Josh van der Flier, Max Deegan.

Lyon team news?

Lyon Team: Kaabèche, Alkhazashvili, Gomez Kodela; Rolland, Roodt; Geraci, Oosthuizen, Bruni; Pélissié, Buttin; Nakaitaci, Regard (cap), Dumortier, Mignot; Arnold.
Replacements: Maurouard, Chaume, Yameogo, Halaifonua, Lambey, Hidalgo-Clyne, Moura, Tuisova.
What's on the line?
Leinster have won all four of their pool games up until this point, earning three bonus points in the process. They are well primed to earn a home quarter final, finishing off the group with a trip to Benetton.
Lyon will likely require a big win to keep any slim hopes of reaching the quarter final stages alive, with the French side currently sitting in third place behind Northampton.
The game will also be keenly observed by new Ireland coach Andy Farrell with the Six Nations only a few weeks away. Places in the starting XV for the game against Scotland, and in the squad for the tournament itself, will no doubt be up for grabs.
