James Morgan, Ben Crealey and Shane McPartlan have all been handed starts for Armagh’s clash with Antrim on Saturday.
Rian O’Neill and Andrew Murnin haven’t been named in the squad, having picked up injuries in recent weeks.
Jarly Og Burns, who hasn’t missed a championship game since making his debut in 2019, also isn’t named in the starting line-up.
Morgan and Crealey were key members of the team last season when Armagh reached the All-Ireland quarter-finals.
The pair missed the entire National League campaign through injury but are back to full fitness just in time.
Morgan had lined out for Crossmaglen in their recent 3-15 to 0-11 victory over Killeavy and gained some essential match sharpness.
Shane McPartlan will made his Championship debut against Antrim, with the Clan na Gael man starting at midfield.
McPartland made his Armagh debut against Antrim in the McKenna Cup earlier in the year and kicked 0-1.
His only league appearance came in the dying moments of Armagh’s two-point defeat to Tyrone in the final round.
Barry McCambridge will also make his championship debut having impressed throughout the league.
The Clann Eireann defender held David Clifford and Shane Walsh scoreless from play in two of his most eye-catching performances.
Ethan Rafferty once again retains the number one shirt with Morgan, Aaron McKay and Aidan Forker in the full back line.
McCambridge starts at wing half back but is likely to drop back into the full back line. Greg McCabe and Ciaran Mackin complete the half back line.
There’s a new pairing a centerfield, with Crealey and McPartlan lining out in the number eight and nine jerseys.
Rory Grugan, who claimed his first ever goal in the Ulster Championship against Antrim two years ago, is centre half forward.
He’ll be flanked by Stefan Campbell and Jason Duffy, who complete Armagh’s half forward line.
Jemar Hall impressed when played closer to goal against Tyrone and starts the game at corner forward.
Conor Turbitt, Armagh’s top scorer the last day out in Omagh with 0-5, claims the full forward spot.
Tiernan Kelly, who netted against Antrim on his championship debut in 2021, will start at corner forward.
