It's all go tonight as the RaboPro12 semi finals rolls around. You can catch all the action on both RTE Two and TG4 from 7.30pm this evening, as Ulster take on Scarlets at Ravenhill. The Ulstermen have only lost one of their last six games in the competition, and they're on home ground: Will they sail through to the semi-final? The Welshmen certainly won't go down without a fight though, what with this being their first appearance in the Play-Offs and all... Action on the pitch kicks off at 7.45pm
