Free kick to red after an early engagement at the scrum, just inside the scarlets half. They take it quickly

Interesting face off at 10 here today. Two welsh internationals looking to make a mark. Dan Biggar undoubtedly No. 1 at the moment but can Biggar make something of this opportunity.....

We are up and running here, Rhys Priestland with the KO.

KO not far away, stay tuned for live updates.

While Ospreys returned to the top of the GUINNESS PRO12 table with a 31-20 home win over Ulster, Scarlets slipped to defeat at Cardiff Blues for a second successive loss. And the history books suggest that they could lose three in a row for the first time in a year since they have not won away from home in any competition since a trip to Treviso in February. They have not upset a fellow Welsh region at their regular home ground since beating Blues at the Arms Park in December 2012. Scarlets' only victory over Ospreys in their last dozen encounters was 22-12 at Parc y Scarlets on Boxing Day 2011, whilst the only occasion they have ever been triumphant at Liberty Stadium came on September 11 2007

Hello and welcome to Ultimate Rugby's live coverage of the Pro 12 with Ospreys playing host to Scarlets here in the Liberty this evening.
