Preview/Team News: Coaches Andy Hughes and Bevan Lynch have picked along expected lines for this all-Ulster clash, with very few weaknesses in the respective Armagh and Derry line-ups.
Player-coach Hughes will take his place in the Armagh back row, while Derry have Mark O'Connor lining out on the left wing fresh from his heroics in kicking Ulster past Munster and into the Irish Colleges Interpro final.
Armagh and City of Derry are both bidding to become the first Ulster club to be crowned AIB Junior Cup champions since Rainey Old Boys won the final in 2006.
With the pair of them riding high in the Ulster Qualifying League and promotion to the senior ranks remaining a serious goal, Saturday's cup final offers a chance to make some history and lay down a marker for the remainder of the season.
Derry defeated Monivea from Galway 26-11 in the recently refixed semi-finals, while Armagh defeated the current champions Tullamore 21-8 to book their place in the decider.
Armagh and Derry have been the kingpins in Ulster junior rugby for the last two years, with Derry coming out on top last year with four victories over their northern opponents - two on their way to winning the Kukri Qualifying League and the other two came in the Towns Cup and the Junior Cup with City winning both trophies.
Armagh are currently flying high at the top of the Kukri Qualifying League, ten points ahead of Derry but having played two games more than their north west opponents.
Armagh and Derry have posted one victory over each other already this season, with both sides winning their home Kukri Qualifying League fixtures.
Saturday's showdown will, judging by past games between these rivals, be a closely contested affair with the result probably in doubt right to the finish.
The performances of the respective out-halves could swing it either way. Armagh's number 10 Adam Gowing was the standout player when the teams met in their first league game in Armagh when they defeated Derry 24-13.
