And we're off! 

Approaching throw-in and the big team news for Donegal is that Jason McGee is fit to take his place in the starting XV. The Cloughaneely man limped off against Cork in the All-Ireland group stages and missed subsequent outings against both Clare and Louth. 

Naomh Columba's Aaron Doherty and Caolan McColgan of Naomh Padraig Iskaheen also start for Donegal with Jeaic Mac Ceallabhuí, Daire O Baoill and Niall O'Donnell now among the replacements.

Donegal: Shaun Patton; Ciaran Moore, Brendan McCole, Eoghan Ban Gallagher; Ryan McHugh, Caolan McGonagle, Peadar Mogan; Ciaran Thompson, Michael Langan; Caolan McColgan, Shane O'Donnell, Jason McGee; Patrick McBrearty, Oisin Gallen, Aaron Doherty.

Galway: Connor Gleeson; Johnny McGrath, Sean Fitzgerald, Jack Glynn; Dylan McHugh, Liam Silke, Sean Mulkerrin; Paul Conroy, Cein Darcy; Matthew Tierney, John Maher, Cillian McDaid; Robert Finnerty, Damien Comer, Shane Walsh.
