Biggar gets us underway

They are closely followed by Nacewa and his Leinster side!

Ospreys take to the field, led by captain Alun Wyn-Jones!

Hello all and welcome to Ultimate Rugby's coverage of this Pro12 clash between Leinster and league leaders Ospreys at the RDS. What an encounter we have in store for us this evening, with both teams studded with international stars. For Leinster, they welcome back the likes of Healy, Sexton, and Heaslip, who all start. Visitors Ospreys shift Sam Davies to full-back, and start Dan Biggar at fly-half. Captain Alun Wyn-Jones is due to start his 200th game for the club. The match-up of the evening is arguably Biggar vs. Sexton, which is likely to be a thrilling clash. A win for Leinster today will see them break into the top 4 whereas Ospreys will evidently be looking to extend their commanding lead at the top. We're almost all set to go here at the RDS!

Will be a tough game for us (ospreys) but if we carry our recent form into the game then we've got a chance.

A big risk for Ospreys leaving players who have started this season so well on the bench. Dan Evans, Dafydd Howells and Sam Parry must be gutted not to be starting.

Strong bench for the Ospreys

Going to be a tight game i reckon.
