ULSTER (2nd) v STADE FRANCAIS (1st), Ravenhill, 1.35pm (live Sky Sports 2)
Team News: Ulster coach Brian McLaughlin has made four changes - three of them in the forwards - for Saturday's Heineken Cup Pool 4 tie with Stade Francais.
Ireland internationals Andrew Trimble and Stephen Ferris come back into the Ulster team, after missing last weekend's Magners League loss to Glasgow Warriors.
Trimble replaces the injured Timoci Nagusa on the right wing, while Ferris returns from injury at number 6, with David Pollock moving to openside flanker and number 8 Chris Henry captaining his province once again.
The two other personnel changes made by McLaughlin see Nigel Brady starting ahead of Andy Kyriacou at hooker and Ed O'Donoghue gets the nod over Ryan Caldwell in the second row.
A knee injury has sidelined South African prop BJ Botha for this crucial clash, so Declan Fitzpatrick continues in the tighthead role.
Commenting on Saturday's game, McLaughlin said: "We know how good Stade Francais are, we know they are a great side with great ambitions for the season. But we have the same ambitions.
"We have them here in Belfast on Saturday, and we have just got to get out onto the pitch and play. We have to out-play them by being accurate and smart, and taking the home advantage. We have to be fearless."
Meanwhile, Stade Francais coach Jacques Delmas has made five changes to the team that secured a 34-10 win at home to Bayonne in the Top 14 Championship last weekend.
Ollie Phillips and Geoffroy Messina return in the back-line for Julien Arias and Guillaume Bousses who have dropped to the replacements bench.
Experienced prop Sylvain Marconnet comes in for David Attoub in the front row, while English duo Tom Palmer and James Haskell will both start in Belfast.
With Argentinian Juan Manuel Leguizamon not being risked after picking up an injury against Bayonne, Palmer joins Arnaud Marchois in Stade's second row and Pascal Pape will anchor the visitors' scrum at number 8.
Lionel Beauxis and former Leicester scrum half Julien Dupuy will pull the strings for Stade at half-back, with grizzled loosehead Rodrigo Roncero captaining the side in the injury enforced absence of Sergio Parisse.

Pre-Match Quotes: Jeremy Davidson (Ulster) - "I think it will be very important for us to give Stade a warm welcome up front, in the early exchanges, so that we can set our stall out, against what is essentially a very strong international team.
"If Stade get it right on the day, not only are they one of the best sides in France, they are one of the best in Europe.
"They are an exceptionally good team with world class players in every position. There is no room for errors in play or set pieces come Saturday.
"The French are very, very passionate about rugby, and French rugby teams historically have based their game around a big pack of forwards dominating and winning the ball, then out in the backs they have the French flair for throwing the ball around.
"Stade Francais exemplify this ethos to a tee, they play a real French style of rugby even though they have been coached by some foreign coaches over the past few years.
"They have also managed to keep a nucleus of French national players in their squad together with a number of top foreign internationals added for good measure.
"Their set piece is very dominant, their scrum, lineout, the maul and then out in the backs they are lucky to have a vast amount of talent to call upon, such as Lionel Beauxis at out-half, Julien Dupuy at scrum half and Mathieu Bastareaud, the big French centre. It is not surprising they have a tremendous running game.
"So, really it is a complete package you come up against whenever you are playing a team of this calibre from the French league."
Julien Dupuy (Stade Francais) - "We will try to reach the quarter-finals - that is what we'll concentrate on. But for the moment, we are happy. We are first in the pool and we've won our opening two games.
"We will just try to play well for the remaining games in our pool. We go to Ulster on Saturday and that will be a big challenge, it will certainly be hard to win there.
"After the first game against Edinburgh, we wanted to produce a big performance against Bath because we knew they are a very physical team".
"It was a good win for us but it's very difficult to think about reaching the final (in Paris) because there are a lot of big teams who want to get there as well."
