Leinster playing numbers game with Joey Carbery

Leinster travel to third-placed Ospreys, keen to keep their hold on a Guinness PRO12 playoffs home semi-final, and Carbery is just one of a host of positional and personnel changes made by Leo Cullen from the side which defeated Wasps in the Champions Cup quarter-final.
Fergus McFadden makes his fifth start of the season, after his try-scoring impact against Wasps off the bench, while hooker Seán Cronin makes his first senior start since January, when a hamstring injury in the routine win over Zebre brought a premature end to his Six Nations hopes. Josh van der Flier comes into the starting lineup, having missed out against Wasps, while Rory O’Loughlin starts on the wing, with Adam Byrne out with the hamstring injury that cut short his involvement in the Aviva Stadium clash. Dave Kearney takes the No23 shirt, hopeful of making just his third appearance since October, due to injury, just in time to push for inclusion at the business end of the season.
