**Ulster know they cannot afford a slip-up against Ospreys at the Kingspan Stadium as they attempt to end Leinster’s dominance in the Guinness PRO14.** They are five points behind champions Leinster, who they meet at this venue on Saturday March 6 in a crunch encounter. Ospreys hold a 15-point advantage in the race to finish in the European places and posted a 10-0 home win over Zebre in atrocious conditions last time out. It was a fourth successive win in the competition for the Welsh side since going down 16-14 at Scarlets on Boxing Day.
