The Blues have moved a mile-and-a-half across the Welsh capital to join forces with Cardiff City FC at the new, 26,000 all-seater Cardiff City Stadium.
Elsewhere on Friday night, the Ospreys travel to the Sportsground in Galway to face Connacht looking for a repeat of the victory they claimed in the same fixture last season.

On Saturday, Leinster are the visitors at Parc y Scarlets - the European champions have won on their last two visits to Llanelli.
The round wraps up on Sunday with the fixture between Newport Gwent Dragons and Ulster with the visitors looking for their first victory at Rodney Parade in three years.
This season's Magners League will welcome 'home' British & Irish Lions Chris Cusiter (Glasgow) and Nathan Hines (Leinster) from sojourns in France, as well as another 2005 Lion, Gareth Cooper (Blues).
