Leinster looking ever more dangerous in the wider channels as this game progresses. Cardiff standing to the test thus far.

PENALTY CARDIFF: Halfpenny makes no mistake this time with a kick from close range. Leinster give away a penalty inside their own 22 after some good pressure from the Blues, who seem to be growing more into the game after a poor start.

PENALTY LEINSTER: Madigan slots another as Cardiff are penalized for holding on at the ruck. Leinster lead now by ten.

PENALTY LEINSTER: Madigan extends Leinster's lead further with a penalty from distance after Cardiff infringe at the ruck.

TRY LEINSTER: Sean Cronin with a superb line out wide, angling back in to go over for the first try of the game. O'Driscoll's light hands placed the ball into Cronin's path after some patience from the Leinster attack. Madigan converts the extra two points to extend Leinster's lead to five.

CARDIFF PENALTY: Halfpenny converts the resulting penalty from Heaslip's shoulder charge. A lucky man to still be on the pitch.

Heaslip spotted by TMO for a shoulder charge. No card awarded.

Leigh Halfpenny with a rare miss form his trusted right boot. The penalty seemed to be just outside his range as the ball drops short and right of the posts

Good evening and welcome to our coverage of Leinster vs Cardiff from the RDS. The weather is ideal here tonight for free flowing rugby. Both sides will be looking to make the most of tonight's encounter. Leinster will be looking to get their season back on track in the league, after losing narrowly last week to Glasgow. The home side will have to up their game if they want to get a win on the board. Cardiff have also struggled thus far this season and will be looking for a rare away win in the Rabo. Both sides have returning Lions to their starting line-ups, Leinster in O'Driscoll, and Kearney both return, and Warbuton and Halfpenny return for the Blues. An exciting game in store for neutrals and fans alike.
