Ospreys bid for league title
On the eve of a Triple Crown decider between the nations, the Ospreys will be crowned champions if they defeat the Gwent Dragons at Swansea (7.05pm) and Munster fail to get a point from their game against Ulster in Musgrave Park (7pm, Setanta Sports).
However, if Munster can keep their unbeaten home record this season alive, the title fight will go on. Alan Gaffney's side are the only undefeated outfit at home in the competition this season their last reversal on home soil in any competition was to Edinburgh at Cork last April.
