All four Irish teams are already qualified for the last 16.
Connacht joined Munster and Ulster in securing qualification with the cancellation of Toulouse v Cardiff ensuring that the western province could not be knocked out of the top eight in Pool B, regardless of what happens in their meeting with Stade Francais on Sunday.
Meanwhile Leinster did the business away to Bath in Saturday's early kick-off.
For Munster to finish in the top two of Pool B, they will need to better the result of either Leicester Tigers or Harlequins. Johann van Graan's side welcome a rejuvenated Wasps to Thomond Park, with the English side bouncing from recent wins against Leicester and Toulouse, having seen their injury troubles ease.
All games are live on BT Sport.
RTE.ie/sport will have live scoring and blogs with match reports and reaction from the grounds.
Connacht fans travelling to Paris should expect dry afternoon with temperatures of 3-5C. It's expected to be quite calm in Limerick on Sunday afternoon where Munster host Wasps, with a dry day expected and temperatures of 8-9C.
Following last week's agonising defeat to Leicester at the Sportsground, Connacht will be hoping to bounce back in style in Paris.
If they can produce anything close to a repeat of their previous encounter with Stade at the Sportsground in December, they should be well on their way to improving their seed for the knockout stages.
Andy Friend's side were 39-9 winners when the sides met in round one, with Stade playing a similar kicking game to the one Connacht will have faced in recent weeks against Leicester and Munster.
Another area of optimism for Connacht is the 4G pitch at Stade Jean-Bouin, which should provide an ideal platform for them to play the running game they are best suited to.
The French side have won 35 of their 36 home games in the pool stage of the Heineken Champions Cup, their only defeat coming against Harlequins in 2008/09 (10-15).
Meanwhile, Connacht have lost their last seven away games in the competition, but the last three defeats came by margins of fewer than seven points.
Stade look much stronger than their December line-up, with Ngani Laumape and Clement Castets adding bulk to their squad, while Connacht are without Finlay Bealham, Ultan Dillane, Kieran Marmion and Bundee Aki.
Stade Francais: Kylan Hamdaoui; Telusa Veainu, Ngani Laumape, Léo Barre, Adrien Lapegue; Nicolas Sanchez, William Percillier; Clément Castets, Tolu Latu, Paul Alo Emile; Mathieu De Giovanni, Paul Gabrillagues; Charlie Francoz, Sekou Macalou, Tala Gray (c).

Six weeks ago it looked like Munster's season had exploded into life when their patched-up team hammered Wasps in Coventry, but while they have won three of their four games since, their performances have not been convincing.
They scored four tries that afternoon, but have crossed the line just five times in the four games since.
Despite their performances, a place in the quarter-finals is already assured, with just their seeding left to be determined.
Wasps have picked themselves up from that defeat in December, and with the help of some key players returning from injury they have beaten Toulouse and Leicester Tigers in recent weeks.
However, they will be without out-half Jacob Umaga for the trip to Limerick after his red card against the defending champions a week ago.
Sunday's game will be the sixth between the sides in this competition, with Munster leading the rivalry by three to two.
Munster: Mike Haley; Andrew Conway, Chris Farrell, Rory Scannell, Keith Earls; Ben Healy, Conor Murray; Dave Kilcoyne, Diarmuid Barron, Stephen Archer; Jean Kleyn, Tadhg Beirne; Peter O'Mahony (c), Jack O'Donoghue, Gavin Coombes.
Replacements: Scott Buckley, Jeremy Loughman, John Ryan, Fineen Wycherley, John Hodnett, Craig Casey, Jack Crowley, Simon Zebo.
Wasps: Ali Crossdale; Marcus Watson, Paolo Odogwu, Ryan Mills, Josh Bassett; Charlie Atkinson, Dan Robson; Tom West, Tom Cruse, Elliott Millar-Mills; Elliott Stooke, James Gaskell; Brad Shields (c), Thomas Young, Nizaam Carr.
