BBC Sport - Pro12 highlights: Leinster 8-3 Ulster
Pro12 action: Leinster beat Ulster
- From the section Rugby Union
Ulster fall to an 8-3 defeat to derby rival Leinster at the RDS dropping down to sixth place in the Pro12 table.
Jonny Sexton and Paddy Jackson traded first-half penalties before Leinster hooker Sean Cronin crashed over in the 37th minute for the game's only try.
Neither side scored in the second half of a dour, slow-paced game in which defences were on top.
