Galway host Derry in the opening round of the All-Ireland Championship group stages on Saturday at 5.30 pm in Pearse Stadium and manager Padraig Joyce has made two changes from the side that beat Mayo in the Connacht final last Sunday week. John Maher and Shane Walsh come in from the start in place of Kieran Molloy and Cathal Sweeney. When the sides met in the National League in February at the same venue, Mickey Harte's side won by 3-10 to 1-11 but the Galway team lining out tomorrow will have six different players starting from that game, including Man of the Match from the Connacht Final, Damien Comer, as well as Shane Walsh, Liam Silke, and both Jack Glynn and Sean Kelly who came on in the second half of that defeat.
