The quest for All-Ireland League rugby begins on Saturday as the four provincial representatives begin the battle, with the top-ranked side gaining automatic promotion and the runners-up entering a play-off with the 15th-ranked side at the end of the Division 2B campaign.
Last weekend OLBC became the fourth and final team to book their place in the competition held over three of the next four weeks.
The Galway side will take on Munster champions Kanturk at the Sportsground this Saturday at 2.30pm.
Meanwhile, on the Aviva Stadium's back pitch, Wanderers and Clogher Valley will clash in their opening game.
Last season Tullamore secured top spot in the Round Robin series, while Richmond finished second and beat Clonakility in the play-off in west Cork.
There are two key fixtures in Connacht this weekend as the promotion and relegation play-offs take place.
In Castlebar on Sunday, Ballina will look to preserve their top flight status against Ballyhaunis who are looking for a spot in Division 1A for the first time in the club's history. The odds are stacked against the east Mayo men.
Meanwhile, the Division 1B/1C play-off takes place in Tuam as the students from NUIG look to topple Corrib.
It is the second year in a row that the Headford-based club have ended up in a play-off to preserve their second tier status. Last year they got the better of Sligo's second team.
Last weekend, Kilkenny, Wicklow and Enniscorthy booked their places in the semi-finals of the Provincial Towns Cup to take place on March 30.
The final spot will be decided on Sunday with unbeaten Division 1B champions Ashbourne up against Division 2A side Roscrea at Miltown House. The winners will take on Enniscorthy in the semi-final.

The Kildare side suffered a heavy loss in Towns Cup action in Kilkenny last week and are looking to bounce back against the men from Sydney Parade who are hoping to end a two-year hiatus outside of the top tier.
The Metro Division 1 final takes place on Sunday at Castle Avenue as table toppers Clontarf host St. Mary's College. This is likely to be a high octane and gripping contest with the northsiders slightly favoured.
The Metro Division 4 final also takes place in Ballycorus on Friday as Old Wesley thirds face Old Belvedere thirds.
Keep an eye out also for action in the Provincial Towns Seconds Cup across the province and in the Albert O'Connell and Moran Cups throughout Dublin over a busy weekend of rugby action.
The Munster Junior Cup takes centre stage this weekend with 22 teams battling for a place in the next round. Holders Garryowen and perennial favourites Cork Constitution are at home to Thurles and Tralee respectively and expected to progress to the last 16.
Two of the eleven ties are still round 1 fixtures which have been delayed because of the weather.
The pick of those is the clash of ever-improving Division 2 side Waterford City at home to Old Christians of Division 1. An upset is on the cards in that one, while Dolphin seconds will be too strong for Killorglin.
In the second round fixtures, nothing stands out more than the meeting of Kinsale and Muskerry for potential drama.
The home side are celebrating a first ever promotion to the top flight after a rip-roaring season, while the visitors have finished mid-table in Division 1 after gaining promotion last season. Both will target this.
Beyond that, the Nenagh Ormond v St. Senan's encounter in Tipperary promises to be a gripping affair. The visitors from Shannon town knocked out St. Mary's in the previous round and are targeting more progress.
Elsewhere, Youghal play Skibbereen in east Cork, Killarney have a tough challenge at home to UCC in Kerry, Midleton seconds take on Clonakility at home while Clonmel host Highfield seconds, who toppled Kanturk in round 1.
It is a quiet weekend in Ulster at junior club level with the notable exception of the Gordon West Cup semi-finals taking place on Saturday (2.30pm kick-offs). The competition - reserved for sides in tiers three and four - is always keenly contested and a place in the final at Ravenhill is very much a cherished reward.
In the first semi-final, competition favourites and Qualifying League 3 leaders Holywood are at home to Newry in the semi-final.
The all-county Down match-up could be a great contest with the home side the favourites to progress after an unbeaten league campaign. The visitors have won seven of their 12 games and sit third in the table.
The other semi-final takes place in north Donegal as Letterkenny are looking to continue their tremendous cup run by upsetting Larne in the last-four.
The visitors are sitting second in Qualifying League 3, while the hosts are sixth in the table having won three of their 12 matches. So, it will take a big effort to upset the odds here.
