Armagh turned in a power-packed second-half performance to overcome Fermanagh in the Ulster U20 Football Championship last night.
Goals from Rian O'Neill and Conor Turbitt proved central to the Orchard County's 2-14 to 0-10 victory.
And Tyrone advanced by beating Monaghan 0-17 to 2-8 with Paul Donaghy, Cahir Goodwin and Benny Gallen to the fore.
Down will take on Antrim in this evening at Pairc Esler, Newry (5pm) where the home side will be favourites to advance.
Oisin McConvey will skipper the hosts and their team will include a raft of exciting young talent spearheaded by Daniel McGuinness, Aaron Devlin and Conor McCrickard.
Patrick McCormick will lead an Antrim side that contains a number of players who have already gained prominence at colleges' level, such as Kevin Small and Liam Quinn.
Hugh McGettigan heads up the Saffrons' management team and while acknowledging that his side face a tough task, he is hopeful they can create an upset.
Tomorrow, Donegal and Cavan will lock horns (2pm) in the curtain-raiser to the Derry v Donegal senior clash at Celtic Park.
Meanwhile, Fermanagh hurlers are hoping that John Duffy and Ciaran Rafferty will again spark their attack when they meet Sligo in the Lory Meagher Cup at Tourlestrane today (3pm).
The Ernesiders drew with Cavan last weekend when Duffy potted seven points while Rafferty scored the side's only goal.
Cavan, too, are in action this afternoon when they host Lancashire. In John Sheanan they have a player who can pose problems for the Lancashire rearguard.
