Maire Treasa Ni Dhubhghaill presents all the action from the PRO12 match at the Royal Dublin Society, between two sides looking to challenge for places in the top four. Leinster are undefeated at home in the league this season, while the Scarlets have been inconsistent, leaving them in danger of being cast adrift by the likes of Munster and Glasgow Warriors. Kick-off is at 7.15pm
