Meanwhile, on Wednesday, the Newport Gwent Dragons welcome a team whom they beat on the double last season, Llanelli Scarlets, to Rodney Parade.
Next weekend's round 2 games open with Ulster visiting the Arms Park, where the Cardiff Blues will hope to continue their home winning streak. Ulster will have to overturn recent results as they have not won in the principality for two years.
Also on Friday Leinster host a resurgent Edinburgh team who, following their defeat by European champions Munster last week, will again be looking to overcome Irish opposition.
Edinburgh will have a tough task on their hands as Leinster have not been defeated at home since October 2007.
The final game on Friday night sees the Ospreys visit Glasgow Warriors, where all eyes will be on Dan Parks, should he be selected, to see if he can overtake David Humphreys to become the Magners League all-time top points scorer.
On Saturday in what promises to be the emotional highlight of the weekend, the last scheduled Magners League game takes place at Stradey Park when Connacht are the visitors to the famous old ground.
The round wraps up on Sunday when the Newport Gwent Dragons travel to Musgrave Park.
The Dragons face a difficult task as since March 2003 the only visiting Welsh team to win on Munster soil has been the Cardiff Blues, who did so twice in 2007.
