The final Friday fixture is a Scottish-Welsh clash as Glasgow Warriors travel to Llanelli to face a resurgent Scarlets team who have been in the play-off zone for the past four rounds.
Of the three games on Saturday, the Welsh derby between the Ospreys and Newport Gwent Dragons stands out.
The fifth-placed Ospreys have not been defeated at the Liberty Stadium since last December. In addition, the Dragons have never won on Ospreys soil.
Connacht travel to Italy hoping to put a stop to their slide down the table having led after the first round. Benetton Treviso, however, are proving impressive on their home soil, having won three of their four home games to date including a notable success over last season's beaten finalists, Leinster.
Leinster are involved in the remaining game on Saturday, welcoming Edinburgh to the RDS, a ground where the home side have a formidable record having not lost a regular season game there since September 2008.
