Connacht v Racing 92 (20:00 BST)
One of the most eagerly anticipated clashes tonight will be in the centres.
Connacht have gone for an explosive mix of youth and veteran, with 21-year-old Hugh Gavin being selected at no.13 alongside international Bundee Aki who turned 35 just last week.
The Parisians have went for Fijian guile in the form of deadly-duo Vinaya Habosi and Josua Tuisova as they aim for a place in final four.
Get ready for some big collisions and cheeky offloads when these two pairs collide.
Connacht v Racing 92 (20:00 BST)
It was a good weekend for Leinster in the Investec Champions Cup, but not for Munster.
Leo Cullen's side enjoyed a 52-0 home win against Glasgow Warriors on Friday to book their place in the semi-finals where they will face either Northampton.
Munster, however, were dumped out of the competition earlier today after a 47-29 defeat against Bordeaux in on Saturday.
Ulster were not in action after being knocked out by Bordeaux in the previous round.

Connacht have made five changes for this European Challenge Cup quarter-final against Racing 92.
The province got the better of fellow United Rugby Championship side Cardiff in the last 16 last weekend without captain Cian Prendergast.
The blind-side flanker returns to the six jersey for the visit from the Top 14 outfit, with Josh Murphy moving back into the second row for the tie.
He will be partnered by former Bristol Bears lock Joe Joyce, who also missed the game against Cardiff.
Prop Denis Buckley starts at loose-head prop, while scrum-half Ben Murphy is fit again after finger surgery.
Shayne Bolton will miss out because of a quad strain with his place on the wing to be taken by Shane Jennings.
The visitors, who are 10th in the Top 14, have named former England captain Owen Farrell on the bench.
The ex-Saracens fly-half started against Perpignan last weekend but England Under-20s playmaker Dan Lancaster - the son of former England coach Stuart - has been handed the number 10 shirt.
Connacht: Hansen; Jennings, Gavin, Aki, Treacy; Hanrahan, B Murphy; Buckley, Heffernan, Bealham, J Murphy, Joyce, Prendergast (capt), Hurley-Langton, Jansen.
Replacements: Tierney-Martin, Dooley, Aungier, Dowling, Boyle, Devine, Ioane, Forde.
Racing 92: James; Naituvi, Habosi, Tuisova, Spring (capt); Lancaster, Le Garrec; Ben Arous, Escobar, Bamba, Palu, Rowlands, Baudonne, Kpoku, Joseph.
Replacements: Couly, Gogichashvili, Leota, R Taofifenua, Manyarara, D Taofifenua, Farrell, Chavancy.

Connacht beat Cardiff 35-20 in the last round after claiming top seeding with three wins in the pool stages.
The French side, meanwhile, finished fifth in their Investec Champions Cup pool but boast plenty of talent.
If Connacht win they will have home advantage in the final four against Lyon.

It was not to be for Ospreys, who are the final Welsh team to bow out of European action this season.
Lyon are through to the final four, but who will they face next?
That question will be answered in the next few hours, as Connacht take on Racing 92.
Stay with us here on BBC Sport online for all the latest from the third quarter-final of this action-packed Saturday.
FT: Ospreys 18-20 Lyon
Jac Morgan has his hands on his head out on the field, he did all he could with a try to his name and several key turnovers, but it was not enough on the night.
FT: Ospreys 18-20 Lyon
Ospreys arguably had the better of proceedings, but a missed opportunity at the end of the first half and Dan Edwards' missed conversion meant they were always behind on the scoreboard.
Lyon march onto the semi-finals. They will face the winner of Connacht v Racing 92.
Ospreys 18-20 Lyon
Lyon are happy with the ball staying in this driving maul, the seconds are ticking away for Ospreys.
Ospreys 18-20 Lyon
It is that man again, Mickael Guillard, who has caused Ospreys all sorts of issues at the breakdown since coming on at half-time.
He wins yet another penalty, and Lyon opt to kick to the corner rather than extend their lead.
Into the final minute.
