Preview: Pro12, Round 22
With just four points separating the top three teams who have already qualified for the Pro12 play-offs, no-one can yet be certain of their position in the table.
With all six games being played on Friday, the focus of attention will be in Ireland, as Glasgow Warriors face Connacht at the Sportsground in Galway, whilst Ulster welcome Cardiff Blues to Ravenhill.
A win for Ulster will put them well clear at the top of the table, anything less and they have to start looking over their shoulders at what their nearest rivals are doing.
Glasgow Warriors are the only one of the top three playing away from home, and carry the added disadvantage of having won one game less than the two team who are above them, so must go all out for a win and see what happens elsewhere to secure home advantage in the knockout stage.
The pick of the final round of this Pro12 campaign must be the repeat of last season's final, when Leinster host Ospreys at the RDS in Dublin.
Leinster have already secured a play-off spot, the question is whether it will be home or away, whilst Ospreys must win, and other results go their way, if they are to snatch the fourth and final play-off place from Welsh neighbours, Scarlets.
Scarlets, four points clear of Ospreys and one win to the better of their rivals, have the added advantage of playing their last regular season game at home, but even so must be wary as they lost to Benetton Treviso in the reverse of this fixture earlier
in the season.
Come 22.00 on Friday, all the questions should answered.
We look at all the Round 22 action!
