**Cian Healy returns to the Leinster starting XV from Ireland duty as they host the Ospreys on Saturday.** Leo Cullen's men - who also welcome back Jordan Larmour and Ryan Baird from the Irish squad - are part of a four-way battle to end the weekend at the top of the overall standings, with Ulster, Glasgow Warriors and Edinburgh also in the running. Sean Cronin could make his 200th Leinster appearance off the bench, while there is also a welcome face among the Ospreys replacements. Dan Lydiate is set to make his return from injury after just over a year out, while Gareth Anscombe - also on the away bench - could reach 500 United Rugby Championship points after being released from the Wales squad.
