Jeaic Mac Ceallabhui has been handed a first championship start for Donegal, while Galway are unchanged for Sunday's All-Ireland football semi-final.
Mac Ceallabhui, from Naomh Conaill, is named at wing-forward for Conor O'Donnell, who drops out of the matchday 26.
Though yet to start in the championship, Mac Ceallabhui did come off the bench to score in the Ulster final against Armagh and played the last 20 minutes against Louth in the quarters.
Padráic Joyce has named an unchanged starting XV from the side that ended Dublin's reign in Croke Park less than a fortnight ago, with Sean Kelly and Shane Walsh both down to start despite being withdrawn with apparent injuries in the last-eight game.
There is a change to the matchday panel, however, with Cian Hernon, introduced in the closing stages of the victory over Dublin, ruled out through injury. Cathal Sweeney, returning from injury himself, takes his place on the bench, as does 2022 All-Star centre-back John Daly.
Donegal: Shaun Patton; Ciaran Moore, Brendan McCole, Eoghan Ban Gallagher; Ryan McHugh, Caolan McGonagle, Peadar Mogan; Ciaran Thompson, Michael Langan; Jeaic Mac Ceallabhuí, Shane O'Donnell, Daire Ó Baoill; Patrick McBrearty, Oisin Gallen, Niall O'Donnell.
Galway: Connor Gleeson; Johnny McGrath, Sean Fitzgerald, Johnny Glynn; Dylan McHugh, Liam Silke, Seán Mulkerrin; Paul Conroy, Seán Kelly; Matthew Tierney, John Maher, Cillian McDaid; Rob Finnerty, Damien Comer, Shane Walsh.

Kerry and Armagh have both name unchanged teams for their All-Ireland SFC semi-final at Croke Park on Saturday.
The Kingdom came through a dour tussle with Derry, while Armagh had a bit too much for Roscommon in their respective quarter-final encounters.
Cillian Burke and Killian Spillane, who both impressed when coming on against the Oakleafers, have again been kept in reserve by Jack O'Connor.
Similarily, Kieran McGeeney has opted not to start Stefan Campbell, this after the Clan na Gael clubman showed well off the bench a fortnight ago.
Kerry: Shane Ryan; Paul Murphy, Jason Foley, Tom O'Sullivan; Brian Ó Beaglaioch, Tadhg Morley, Gavin White; Diarmuid O’Connor, Joe O’Connor; Tony Brosnan, Paudie Clifford, Dara Moynihan; David Clifford, Sean O’Shea, Paul Geaney.
Armagh: Blaine Hughes; Peter McGrane, Aaron McKay, Paddy Burns; Barry McCambridge, Tiernan Kelly, Aidan Forker; Niall Grimley, Ben Crealey; Oisin Conaty, Rian O'Neill, Joe McElroy; Rory Grugan, Andrew Murnin, Conor Turbitt.
