Monkstown, Suttonians, Newbridge and Midland Warriors all won their Leinster League promotion/relegation play-offs last weekend, while Wicklow and Ashbourne made it through to the Bank of Ireland Provincial Towns Cup semi-finals.
In the Metro League, Old Belvedere won Division 1 when they travelled to Lakelands and beat Terenure College 23-17 on Sunday afternoon while in a lunchtime kick-off earlier in the day Dublin University beat visitors Naas 23-16 in College Park to take the Division 2 title.
Trinity College are also promoted to Division 1 on the back of that success and they will replace Blackrock College who lost the relegation play-off 35-21 against Old Wesley at Donnybrook.
Lansdowne are through to the final of the Metropolitan Cup after their 17-10 victory over De La Salle Palmerston at Sydney Parade and they will play the winners of Sunday's second semi-final between MU Barnhall and Monkstown.
Monkstown won the Leinster League Division 1A/1B promotion/relegation play-off when they hung on to beat Clondalkin 32-28 at De La Salle Palmerston.
Monkstown had bolted out of the traps and scored four first-half tries to lead 29-7 at half-time before Clondalkin launched a terrific comeback that was only halted when they coughed up a five-metre attacking lineout for a crooked throw in with the last play of the game.
Suttonians scored a last-minute try to maintain their Division 1B status after they managed to overcome a stern Co Carlow challenge 17-12 at Edenderry in the Division 1B/2A play-off.
Newbridge led all the way in beating Wexford Wanderers 17-13 in the Division 2A/2B playoff at Tullow, while Midland Warriors were the only lower team to prevail when the Westmeath club beat Ardee 26-17 in the Division 2B/3 playoff at Swords.
Tomorrow Malahide commence their journey in the Ulster Bank League Round Robin with a visit to Omagh, the Tyrone side having won the Ulster crown for the first time since 1997.
After powering their way through the cream of the province to win a first ever Leinster League Division 1A title, Malahide will enter proceedings as favourites to make it to the AIL at the first time of asking but their first test tomorrow is likely to be their toughest and the Dubliners have been disadvantaged with two away fixtures from three games.
They have their lone home tie in Estuary Road tomorrow week against Clonmel before completing their campaign in Ballina on April 22.
The semi-finals of the Bank of Ireland Provincial Towns Cup are on Sunday with Wicklow and Skerries locking horns at Cill Dara, while Edenderry is the venue for the clash of Ashbourne and Tullow.
