Speaking of the scheduling, Director of Celtic Rugby David Jordan said "as we draw towards the culmination of the league stage of the 2009/10 Tournament, the introduction of the Play-Offs mean that there will be more meaningful games than ever before and each team will want to field their strongest possible side to challenge for a place in the top four.
"We are also mindful of giving our teams the best opportunity to progress in other tournaments, and as such consider the fixtures we have agreed as the best solution for all concerned."
