A head injury replacement for Leinster sees Murphy come back on for Douglas.

The quality and standard of this game has been sub-par thus far. Neither side have played to the level we have come to expect of them. Which side can up their game as we enter the final quarter?

Davies adds to his tally following Byrne going off his feet at the ruck. The scores are now level at 12-12.

Real thriller this game.

Penalty Ospreys. Byrne is penalized for going off his feet at the ruck. Davies points to the posts.

A series of kicks from both sets of back three players sees the Ospreys gain territorially as they build the phases inside the Leinster half.

the ref is a blind thicker one and don't know the rules

Gopperth steps up in place of Madigan to slot a straightforward kick and restore Leinster's lead. Better play from the hosts.

Gordon D'Arcy is hit before he receives the ball. Penalty to Leinster right in front of the posts.

But the Ospreys turn the ball over and clear their lines well. Good running from Dave Kearney coming in off his wing was almost rewarded with a try. But good defence from the Ospreys thwarts the Leinster attack.
