Leinster coach Michael Cheika will trim the squad down to the matchday 22 on Friday lunchtime.
The extended squad also includes two more Ireland internationals - former Tigers duo Leo Cullen and Shane Jennings. Chris Whitaker and Ollie Le Roux â00 who have both been in fine recent form â00 are also included alongside prop Stephen Knoop who missed last weekendâ00s game through injury.
Speaking ahead of Saturday's game, Leinster skipper O'Driscoll said: "I always look forward to a new Heineken Cup â00 the great thing about this competition is that it always adds new opportunities. fter the World Cup it is great to have such a tournament to look forward to and now you can really sense the excitement from everyone involved with the Heineken Cup as the start approaches.
â00And while Leicester was always going to be difficult and a tough start for us, you can look at these things two ways. You are probably going to have to win eight out of nine games â00 the last three against some of the best teams that season â00 and, come May, the Heineken Cup winners will be worthy champions.
â00It means that if you win your first game, possibly your first two, then you are sitting pretty and growing in confidence. But lose your first game and the pressure is immediately on and the likelihood in this Pool is lose two games and you will be out.
â00We start with Leicester Tigers at home and then Toulouse away, so we couldnâ00t have asked for two tougher challenges to kick-off with. We know we are in one of the pools of death, but we also know that whoever comes out of the group will have a great chance to build on that success in the knockout phase.
â00So it can work both ways for you â00 and I guess the message is donâ00t start slowly!â0
Leinster will be boosted for the start of their campaign by the return of Felipe Contepomi, who a stunning World Cup with third place finishers Argentina, and Oâ00Driscoll is looking for more of the same from the IRB Player of the Year nominee.
â00Felipe had an excellent World Cup for Argentina and he has been excellent for Leinster for a number of years. Hopefully he can translate some of that form into an all blue jersey rather than a striped one," O'Driscoll said.
"It is great to have a player of his calibre coming in even if he has not played for us yet this season. I am sure he won't be short of fitness - and confidence oozes out of every pore of his body."
