The Ospreys make 13 changes for the trip to Dublin, with Lee Byrne returning at full back
The Ospreys have named a strong line-up for the mouth-watering Magners League showdown with Leinster on Friday night.
Ospreys coach Sean Holley makes 13 changes from the win at Glasgow Warriors as they bid to maintain their unbeaten start to the season.
The Welsh region have won their first three matches but now face a mammoth task against Leinster in Dublin who have won all but one of their last 27 matches at home.
Holley said: "The Magners League is getting tougher year on year and it's great we can take such a strong team.
"Leinster are the benchmark of the league but we usually have tight matches with them and I expect this will be another close game.
"It's really exciting because there will be a sell-out crowd and it will be live on television. This is what we're in the game for."
The Ospreys have already won in Ireland following an opening day victory at Connacht before hammering Welsh rivals Cardiff Blues.
But Ospreys captain Ryan Jones expects his men will have to step their game up a notch to gain a fourth successive win of the campaign at the Royal Dublin Showgrounds.
Jones said: "Every game has been a test. We've put in some good performances so far but Leinster are the champions, and playing like it."

The programme has been funded by the Hunter Foundation.
