It was always going to be touch and go.
With Leinster looking like they have secured passage to the Champions Cup semi-finals after a barn-storming first half display at the Aviva Stadium, attention is beginning to shift down south where Munster face Toulouse in Thomond Park.
Munster are favourites for the game but they have just been dealt a massive blow ahead of kick-off.
It has been confirmed that Conor Murray is not fit enough to play in today's match.

Murray was named in the starting XV on Friday but it was well known that the Limerick man would face a fitness test on Saturday morning to see if he had successfully got over the shoulder injury which he picked up against Wales in the Six Nations.
It looks like the injury is still bothering him and the Munster management don't want to take the risk with one of their most prized assets.
Duncan Williams will have the opportunity on the biggest of stages to conduct proceedings and secure passage to the semi-finals for the southern province.
Angus Lloyd comes in on the bench.
Kick off in this huge match is at 17.45.
