Leaders Armagh determined to keep Greystones at arm's length
There is no doubting the most significant clash over the three divisions as 2B pace-setters City of Armagh host their nearest challengers Greystones.
Just to add to the mix, this game comes a week after Alex McCloy's men saw their nine-game winning streak come to an unexpected halt at Wanderers.
And for all their excellent form until last weekend, Armagh's first taste of defeat in this season's AIL could hardly have come at a more inopportune moment as Greystones are now just four behind the squad overseen by McCloy and former Ulster coach Brian McLaughlin.
Also in 2B, Dungannon, who are in sixth, host ninth-placed City of Derry who travel to Stevenson Park on the back of a win last Saturday over Barnhall.
In 2A, Malone have sprung up to second on the back of winning their last three games and they host Blackrock College with Mark McCrea and Jack Owens in Paddy Armstrong's starting side.
The mood is not just so upbeat at former leaders Banbridge, who have lost their last two games -the back-to-back encounters with Highfield - which now sees Dan Soper's men down in fourth but with only one point separating them from Nenagh Ormond who are in top spot.
Bann are at Galway Corinthians and have Andrew Magrath back from Ulster 'A'.
Fifth-placed Queen's University host bottom side Belfast Harlequins.
In 2C, fifth-placed Bangor travel to Bruff while Rainey Old Boys, who are in second, are at struggling Kanturk.
