Sligo captain Noel McGuire has failed to recover from a dislocated elbow in time for Sunday's crunch Connacht SFC semi-final encounter with Mayo.
The Easkey clubman did the damage in a club league game in late April and was sidelined for the Yeats County's quarter-final win over London in Ruislip last month.
Boss Tommy Jordan has opted to name an unchanged side in McGuire's absence but has tinkered with the shape of his team.
Jonathan Davey has been moved from left half-back to left half-forward after hitting two points last time out.
And Eoin McHugh, who began at full-forward against the Exiles, ss now located in the half-back line.
To accommodate the positional switches, Mark Breheny will act as target man on the edge of the square and Brendan Egan will move from the wing to centre forward for the reigning Connacht champions.
SLIGO (SFC v Mayo) - P Greene; C Harrison, P Naughton, R Donovan; P McGovern, M McNamara, E McHugh; E O'Hara, K Quinn; B Curran, B Egan, J Davey; G Gaughan, M Breheny, D Kelly.
