Leinster continue their preparations for a big derby in the Pro12 this weekend.
They welcome Ulster to the RDS on Saturday night on the back of their loss to Munster on Stephens Day.
There's expected to be wholesale changes in the Leinster team given the 10 made from the side winners over Northampton.
Rory O'Loughlin is one of those hoping to keep their place and says they cant afford another poor loss.
