Team News: The Leinster team to face the Ospreys in Friday night's Magners League showdown at the RDS has been announced.

Cullen will captain the side and has been named in the second row alongside Devin Toner who impressed as a replacement last Friday.
The third change in the pack sees Sean O'Brien come in as openside flanker, joining Cameron Jowitt and Jamie Heaslip in the back row.
In the back-line, Shane Horgan starts on the right wing while the final change sees Isa Nacewa partner Chris Whitaker at half-back.
Luke Fitzgerald, the hat-trick hero from the Edinburgh game, lines up on the left wing with Girvan Dempsey continuing at full-back.
Meanwhile, Ospreys boss Sean Holley has made a massive 13 changes to the team that beat Glasgow 21-18 for this mouth-watering clash with Leinster.
Winger Nikki Walker and lock Alun Wyn Jones are the other players remaining from the side that edged out Glasgow at the Firhill Arena.
Amongst the big-hitters returning to the former champions' line-up are Wales captain Ryan Jones and his international colleagues, full-back Lee Byrne and out-half James Hook.
Star winger Shane Williams is absent from the Ospreys squad due to a dead leg.

Say What: Jonno Gibbes (Leinster forwards coach) - "The Ospreys will bring a big physical pack, 1 through 8. It's going to be vitally important that we meet them head on and we win the gain-line.
"The guys are focused. They had a reasonably good win (over Edinburgh) last Friday and they turned up for training on Sunday and Monday focused, with a good attitude and working hard again.
"The Edinburgh result was indicative of four days great preparation and our Ospreys week has been prepared well, which is a good sign for Friday.
"For me, Edinburgh was a reflection of our Monday to Thursday. We prepared bloody well during the week and Friday was the outcome of how well we had prepared.
"The players were focused and we didn't give Edinburgh an awful lot and we took the opportunities that we created.
"I wouldn't say that we played a whole heap of rugby in that game, but we certainly converted the opportunities that we did create, and I think that was a real positive.
"The fact that we got 20-odd points ahead and didn't take the foot off the gas was also a positive for us."
Sean Holley (Ospreys) - "Friday night looks likely to be a cracking occasion, two in-form sides locking horns in front of a near sell-out crowd.
"We're all really excited about it, it's matches like this that we are all involved in rugby for. The matches between the two of us have generally tended to be close affairs over the years and I wouldn't expect it to be any different this time around.
"When you look at the Leinster side, they are the Magners League champions, they are packed with quality and experience and they have threats right across the field so the size of the challenge that lies ahead of us if we are to get a result over there is clear.
"They have forwards who seem to deliver week in, week out, a first class defence and individuals of real ability behind so we know that we have to be on top of our game.
"However, we go into the game with confidence high after three straight wins and I don't doubt for one minute that they will look at the side that we've named and think exactly the same thing, so it's bound to be an intriguing clash."
