Again, no official confirmation yet, but looked as though he was holding his knee.

What happened Donnacha? They made sure to block the camera.

Munster dominating the game at the moment, not allowing Leinster out of their 22 easily. The pack especially look dominant with great performances so far from O'Mahony and O'Donnell. 55 minutes gone Leinster in possession in the Munster half.

Leinster kick the ball to touch from a penalty to get into Munster territory. After a sniping run from boss O'Connell is adjudged to have used hands in the ruck while not supporting his body weight and is penalised. Madigan converts.

Can't believe it's taken 47 minutes for the first off their feet penalty. Munster haven't supported their weight at all during the game. Nigel Owens having an unusually awful game

With Leinster on the attack just inside the Munster half, Ross goes clearly in at the side. Keatley takes a shot at goal from inside is own half and hits a great penalty which sneaks over. 45 minutes gone.

Leinster fail to claim the ball from the restart, knocking it on to give Munster the scrum. At the scrum Ross is penalised to give Keatley an easy kick to give his side the lead. 43 minutes gone.

Referee Nigel Owens calls time on an interesting first half of rugby. Munster go in behind but will be happy with their half which was played into a stiff breeze which will help them in the second half. Both sides are showing good organisation and intensity in defence and so its no surprise that defences are dominating proceedings. With just 2 points separating the sides all is still to play for in what should be an exciting second half.

With Leinster on the attack Varley is penalised for not rolling away. Madigan makes no mistakes from the penalty to reclaim the lead for his side. 34 minutes gone.

Blatant obstruction
