Con and Cookies in semi-finals
Cork Con are aiming to reach back-to-back Ulster Bank League Division 1A finals when they travel to take on Lansdowne at the Aviva Stadium on Sunday.
Con lost last year's decider 28-25 to Clontarf; the Cork outfit, who are four-time winners, haven't claimed a league title since 2010.
They finished in the fourth and final play-off position despite last weekend's 34-27 victory at home to St Mary's.
Young Munster hammered already relegated Old Belvedere 33-12 in the final round, and in the other final four clash they make the difficult journey to face reigning champions Clontarf, at Castle Avenue.
In the Division 1B promotion play-offs there are two Munster teams involved, with Garryowen looking to avoid the drop.
They were hammered 40-17 by Lansdowne at the Aviva last weekend and finished second from bottom.
Garryowen host Old Wesley at Dooradoyle, while fellow Limerick side UL Bohemians are away to Naas at Forenaughts - Bohs finished third in Division 1B, a massive 20 points behind runaway champions Buccaneers.
In the Division 2A promotion play-offs there is a big Munster derby in one of the semi-finals, with Highfield hosting Nenagh Ormond at Woodleigh Park.
Highfield finished second in Division 2A, six points clear of Nenagh.
In the second play-off Dolphin, who finished ninth in 1B, are at home against Malone at Irish Independent Park.
