With just five rounds left to decide which teams will contest the Play-Offs, there is a new leader of the RaboDirect PRO12 with Glasgow Warriors taking over the mantle from Ulster, whilst for the fourth round in succession, Ospreys swapped places with Scarlets in the Play-Off Zone.
Three of those teams are in action on Friday night; Ulster traveling to Edinburgh, Ospreys hosting Welsh rivals Newport Gwent Dragons, and Scarlets in Italy to face Zebre.
Edinburgh can do their Scottish neighbours, Warriors, a favour if they can defeat Ulster however their record against the Ulstermen is not great. Meanwhile Ospreys and Scarlets must both be looking to come away with maximum points from opponents who are sitting at the wrong end of the table in their bids to reach the Play-Offs.
The leaders, Glasgow Warriors, are not in action until Saturday, and are the only one of the potential Play-Off teams to face another side from the top half of the table when the visit Leinster at the RDS. Munster will also be looking for maximum points in the All-Irish clash against Connacht if they are to make a final push for the knockout stages.
With just two points separating the top three teams in the table, whilst it is even closer for the final Play-Off spot, there is definitely all to play for still as the RaboDirect PRO12 enters its closing stages.
