Leinster 18-18 Ulster

This is what Luke Marshall brings you. He brings another dimension to his distribution. That finish was so strong, his footwork means he rarely gets smashed. He brings so much energy and organisation.
Luke Marshall
Level!
A lovely pull-back pass from Stuart McCloskey suckers in the Leinster defence and Luke Marshall, just off the bench, has men outside him.
The centre opts instead for the hard road, but straightens and barges through Ross Byrne to score.
John Cooney misses a very gettable conversion and we are all square on the scoreboard.
Leinster 18-13 Ulster
We are back under way. Ulster are probing. Jacob Stockdale drives up to within five metres...
Leinster 18-13 Ulster
Dan Leavy has copped a really nasty one - a badly hyperextended knee.
The medics are on to help him off. But this is going to take some time, and he is going to be out of action for some time.

What a game, this is edge of the seat stuff. It's a stunning game of rugby - the way Ulster have come back again. The players are shattered!
Leinster 18-13 Ulster
Scott Fardy is off his feet at the breakdown.
Ulster have a penalty. Surely the kick for goal from a very presentable position?
Meanwhile we have a stoppage while there is some treatment to Leinster's Dan Leavy.
Luke Marshall is on for Darren Cave in the Ulster midfield as well.

Jacob Stockdale with a delicious chip and gather in midfield as he runs the ball back at the Leinster chase...
Ulster are up to within sight of the Leinster 22m.

This is a tight-rope walk of a final 20 minutes.
Who blinks first?

Richard Mansell: It's an Irish cracker!

It's a difficult time for the coaches, do you keep your experienced players on or put some fresh blood on there? You don't want to force too many changes but there must be an injection of energy at some point.
Leinster 18-13 Ulster
Changes in the Leinster front row.
James Tracey and Ed Byrne come on in place of Cian Healy and Sean Cronin.

Leinster have been so physical at the breakdown. Ulster need to be careful that they're not trying to overcommit to each ruck.
Adam Byrne (con R Byrne)
Leinster with a massive try!
Jack Conan spots some soft underbelly in the fringe defence and ploughs through, finding time to pull his shorts up as he canters into the open plain.
Adam Byrne is motoring up on his shoulder.
Conan feeds him and he scoots into the corner.
Conversion by Ross Byrne.

The worry for Ulster is they're getting caught really narrow with some of the backs close to the rucks. Leinster are getting over the gainline so easily and at the minute Ulster can't stop them.
Leinster 11-13 Ulster
Changes.
Off goes Sean O'Brien for Dan Leavy in the Leinster back row.
While Marcell Coetzee is replaced by Sean Reidy in the Ulster number eight slot.
Leinster 11-13 Ulster
Leinster are now pressing forwards after Sean Cronin's bustling break...and Ulster repel them!
John Cooney is over the breakdown to secure the penalty red.
Rory Best is watching on on crutches from the touchline.

How much might that error count in the final reckoning?
If Ulster don't win this that error will be replaying even more in Stockdale's mind than it did on the TMO's VHS...

Jim Neilly
BBC Radio Ulster commentator
That would have been the try of this or any other season.
