Ulster vs Leinster URC preview as the sides meet at the Affidea Stadium in Belfast.
The Interprovincial sides currently sit third and fourth in the table with the home team currently one point ahead with just four regular season games to go. A win for either side will be crucial to build separation between themselves and the Lions in fifth. The losing side would allow the Lions to catch them and could see Cardiff or Munster close the gap for a home quarter final draw.
