The inclusion of a clause in this season's Tournament Rules requiring any games that have an impact on qualification for the Play-Offs to kick-off the same day and time means that two of the games, Cardiff Blues v Munster and Leinster v Edinburgh, will be played simultaneously.
Three teams have already qualified for the inaugural Magners League Play-Offs, Leinster, Ospreys and Glasgow Warriors, whilst three further teams, Munster, Cardiff Blues and Edinburgh are vying the fourth and final qualifying spot.
