CASTRES OLYMPIQUE v LEINSTER, Stade Pierre Antoine, 9pm local time/8pm Irish time (live Sky Sports 1)
Team News: The Leinster team to face Castres Olympique in Friday night's Heineken Cup Pool 2 encounter at the Stade Pierre Antoine has been named.
Simon Keogh will start on the right wing after scoring a try last weekend, while injury worry Brian O'Driscoll will undergo a fitness test before the game.
Should O'Driscoll fail to recover, Felipe Contepomi will start with Fergus McFadden coming onto the replacements bench.
In the pack, Malcolm O'Kelly continues his second row partnership with Devin Toner, who was the Heineken man-of-the-match in the 33-3 victory over Castres at the RDS last Saturday.
Shane Jennings returns from injury to don the number 7 jersey and the fit-again Isa Nacewa has also been named on the bench.
Several hundred Leinster supporters are expected to make the trip to France for the game.
If O'Driscoll plays in the return match against Castres, he stands a chance of joining the small band of players who have scored 25 tries in the Heineken Cup.
He crossed for his 24th Heineken Cup try in last weekend's victory over Castres.
It was the Ireland captain's fourth try in this season's competition, while his overall try tally has come in 54 matches.
O'Driscoll's Leinster team-mate Shane Horgan is also one try short of the 25-try mark.
Only two players have so far scored 25 Heineken Cup tries or more - Dafydd James (29) and Vincent Clerc (27).

Pre-Match Quotes: Alan Gaffney (Leinster technical consultant) - "Castres will be playing with a different team this week, though we have done analysis on them for the last five or six games before this already.
"So we're pretty much aware of the abilities of each of the players without them announcing their team.
"The two nines play differently and we understand that. So we've got to adopt and adapt to the side that they pick.
"Weâ00ll probably be running about two or three different backlines in training so itâ00s a bit tough in that regard. But weâ00re going to have to keep throwing different people into different positions.
"(In terms of) the passing last week, it was one of the worst performances that we have put in this year. We work on it every training session, so thereâ00s no real reason to suspect as to why it happened.
"A lot of the passing was thrown into the body, which is more a timing issue. We had chopped and changed, but that still shouldnâ00t affect what we did at the weekend.
"By passing the ball the way we did, into the body and into the shoulder, it took all the pace out of what we were trying to do.
"I think we did create a number of chances, but when the pace comes off the game itâ00s a very difficult thing to regenerate. A lot of good things were done to get us to that stage, but little things such as that let us down.
"Thereâ00s no doubt that we probably played the game a bit narrow at the weekend. And I think we have been guilty of that. Thatâ00s something that we have addressed again.
"We have got the ability, we train and we know what we want to achieve. Sometimes weâ00re not backing ourselves to do things, but sometimes we have to set up certain plays and patterns.
"Traditionally speaking, every play we play is one we want to have as a strike play. We put a few things together that we were happy with, but not enough."
